###### action
See [template action](#template-action).
###### archetype
A template for new content. See [details](/content-management/archetypes/).
###### argument
A [scalar](#scalar), [array](#array), [slice](#slice), [map](#map), or [object](#object) passed to a [function](#function), [method](#method), or [shortcode](#shortcode).
###### array
A numbered sequence of elements. Unlike Go's [slice](#slice) data type, an array has a fixed length. [Elements](#element) within an array can be [scalars](#scalar), slices, [maps](#map), pages, or other arrays. See the [Go documentation](https://go.dev/ref/spec#Array_types) for details.
###### bool
See [boolean](#boolean).
###### boolean
A data type with two possible values, either `true` or `false`.
###### branch bundle
A [page bundle](#page-bundle) with an _index.md file and zero or more [resources](#resource). Analogous to a physical branch, a branch bundle may have descendants including regular pages, [leaf bundles](/getting-started/glossary/#leaf-bundle), and other branch bundles. See [details](/content-management/page-bundles/).
###### build
To generate a static site that includes HTML files and assets such as images, CSS, and JavaScript. The build process includes rendering and resource transformations.
###### bundle
See [page bundle](#page-bundle).
###### cache
A software component that stores data so that future requests for the same data are faster.
###### chain
Within a template, to connect one or more [identifiers](#identifier) with a dot. An identifier can represent a method, object, or field. For example, `.Site.Params.author.name` or `.Date.UTC.Hour`.
###### collection
An [array](#array), [slice](#slice), or [map](#map).
###### content format
A markup language for creating content. Typically markdown, but may also be HTML, AsciiDoc, Org, Pandoc, or reStructuredText. See [details](/content-management/formats/).
###### content type
A classification of content inferred from the top-level directory name or the `type` set in [front matter](#front-matter). Pages in the root of the content directory, including the home page, are of type "page". Accessed via `.Page.Type` in [templates](#template). See [details](/content-management/types/).
###### content view
A template called with the `.Page.Render` method. See [details](/templates/views/).
###### context
Represented by a dot "." within a [template action](#template-action), context is the current location in a data structure. For example, while iterating over a [collection](#collection) of pages, the context within each iteration is the page's data structure. The context received by each template depends on template type and/or how it was called. See [details](/templates/introduction/#the-dot).
###### default sort order
The default sort order for page collections. Hugo sorts by [weight](#weight), then by date (descending), then by link title, and then by file path.
###### element
A member of a slice or array.
###### environment
Typically one of `development`, `staging`, or `production`, each environment may exhibit different behavior depending on configuration and template logic. For example, in a production environment you might minify and fingerprint CSS, but that probably doesn't make sense in a development environment.
When running the built-in development server with the `hugo server` command, the environment is set to `development`. When building your site with the `hugo` command, the environment is set to `production`. To override the environment value, use the `--environment` command line flag.
To determine the current environment within a template, use the [`hugo.Environment`] function.
[`hugo.Environment`]: /functions/hugo/environment
###### field
A predefined key/value pair in front matter such as `date` or `title`. See also [parameter](#parameter).
###### flag
An option passed to a command-line program, beginning with one or two hyphens. See [details](/commands/hugo/).
###### float
See [floating point](#floating-point).
###### floating point
A numeric data type with a fractional component. For example, `3.14159`.
###### fragment
The final segment of a URL, beginning with a hash (`#`) mark, that references an `id` attribute of an HTML element on the page.
###### front matter
Metadata at the beginning of each content page, separated from the content by format-specific delimiters. See [details](/content-management/front-matter/).
###### function
Used within a [template action](#template-action), a function takes one or more [arguments](#argument) and returns a value. Unlike [methods](#method), functions are not associated with an [object](#object). See [details](/functions/).
###### global resource
A file within the assets directory, or within any directory [mounted](/hugo-modules/configuration/#module-configuration-mounts) to the assets directory. Capture one or more global resources using the [`resources.Get`], [`resources.GetMatch`], [`resources.Match`], or [`resources.ByType`] functions.
[`resources.Get`]: /functions/resources/get
[`resources.GetMatch`]: /functions/resources/getmatch
[`resources.Match`]: /functions/resources/match
[`resources.ByType`]: /functions/resources/byType
###### identifier
A string that represents a variable, method, object, or field. It must conform to Go's [language specification](https://go.dev/ref/spec#Identifiers), beginning with a letter or underscore, followed by zero or more letters, digits, or underscores.
###### int
See [integer](#integer).
###### integer
A numeric data type without a fractional component. For example, `42`.
###### internationalization
Software design and development efforts that enable [localization](#localization). See the [W3C definition](https://www.w3.org/International/questions/qa-i18n). Abbreviated i18n.
###### interval
An [interval](https://en.wikipedia.org/wiki/Interval_(mathematics)) is a range of numbers between two endpoints: closed, open, or half-open.
- A _closed_ interval, denoted by brackets, includes its endpoints. For example, [0,&nbsp;1]&nbsp;is the interval where `0 <= x <= 1`.
- An _open_ interval, denoted by parentheses, excludes its endpoints. For example, (0,&nbsp;1)&nbsp;is the interval where `0 < x < 1`.
- A _half-open_ interval includes only one of its endpoints. For example, (0,&nbsp;1]&nbsp;is the _left-open_ interval where `0 < x <= 1`, while [0,&nbsp;1)&nbsp;is the _right-open_ interval where `0 <= x < 1`.
###### kind
See [page kind](#page-kind).
###### layout
See [template](#template).
###### leaf bundle
A [page bundle](#page-bundle) with an index.md file and zero or more [resources](#resource). Analogous to a physical leaf, a leaf bundle is at the end of a branch. Hugo ignores content (but not resources) beneath the leaf bundle. See&nbsp;[details](/content-management/page-bundles/).
###### list page
Any [page kind](#page-kind) that receives a page [collection](#collection) in [context](#context). This includes the home page, [section pages](#section-page), [taxonomy pages](#taxonomy-page), and [term pages](#term-page).
###### localization
Adaptation of a site to meet language and regional requirements. This includes translations, language-specific media, date and currency formats, etc. See&nbsp;[details](/content-management/multilingual/) and the [W3C definition](https://www.w3.org/International/questions/qa-i18n). Abbreviated l10n.
###### map
An unordered group of elements, each indexed by a unique key. See the [Go&nbsp;documentation](https://go.dev/ref/spec#Map_types) for details.
###### markdown attribute
A list of attributes, containing one or more key/value pairs, separated by spaces or commas, and wrapped by braces. Apply markdown attributes to images and block-level elements including blockquotes, fenced code blocks, headings, horizontal rules, lists, paragraphs, and tables. See&nbsp;[details](/getting-started/configuration-markup/#goldmark).
###### marshal
To transform a data structure into a serialized object. For example, transforming a [map](#map) into a JSON string. See [unmarshal](#unmarshal).
###### method
Used within a [template action](#template-action) and associated with an [object](#object), a method takes zero or more [arguments](#argument) and either returns a value or performs an action. For example, `.IsHome` is a method on the `.Page` object which returns `true` if the current page is the home page. See also [function](#function).
###### module
Like a [theme](#theme), a module is a packaged combination of [archetypes](#archetype), assets, content, data, [templates](#template), translation tables, static files, or configuration settings. A module may serve as the basis for a new site, or to augment an existing site. See&nbsp;[details](/hugo-modules/).
###### object
A data structure with or without associated [methods](#method).
###### ordered taxonomy
Created by invoking the [`Alphabetical`] or [`ByCount`] method on a [taxonomy object](#taxonomy-object), which is a [map](#map), an ordered taxonomy is a [slice](#slice), where each element is an object that contains the [term](#term) and a slice of its [weighted pages](#weighted-page).
[`Alphabetical`]: /methods/taxonomy/alphabetical
[`ByCount`]: /methods/taxonomy/bycount
###### output format
{{% include "methods/page/_common/output-format-definition.md" %}}
###### page bundle
A directory that encapsulates both content and associated [resources](#resource). There are two types of page bundles: [leaf bundles](#leaf-bundle) and [branch bundles](#branch-bundle). See&nbsp;[details](/content-management/page-bundles/).
###### page collection
A slice of page objects.
###### page kind
A classification of pages, one of `home`, `page`, `section`, `taxonomy`, or `term`. See&nbsp;[details](/templates/section-templates/#page-kinds).
Note that there are also `RSS`, `sitemap`, `robotsTXT`, and `404` page kinds, but these are only available during the rendering of each of these respective page's kind and therefore *not* available in any of the `Pages` collections.
###### page resource
A file within a [page bundle](#page-bundle). Capture one or more page resources using any of the [`Resources`] methods on a `Page` object.
[`Resources`]: /methods/page/resources/#methods
###### pager
Created during [pagination](#pagination), a pager contains a subset of a section list, and navigation links to other pagers.
###### paginate
To split a [section](#section) list into two or more [pagers](#pager) See&nbsp;[details](/templates/pagination/).
###### pagination
The process of [paginating](#paginate) a [section](#section) list.
###### parameter
Typically, a user-defined key/value pair at the site or page level, but may also refer to a configuration setting or an [argument](#argument). See&nbsp;also&nbsp;[field](#field).
###### partial
A [template](#template) called from any other template including [shortcodes](#shortcode), [render hooks](#render-hook), and other partials. A partial either renders something or returns something. A partial can also call itself, for example, to [walk](#walk) a data structure.
###### permalink
The absolute URL of a published resource or a rendered page, including scheme and host.
###### pipe
See [pipeline](#pipeline).
###### pipeline
Within a [template action](#template-action), a pipeline is a possibly chained sequence of values, [function](#function) calls, or [method](#method) calls. Functions and methods in the pipeline may take multiple [arguments](#argument).
A pipeline may be *chained* by separating a sequence of commands with pipeline characters "|". In a chained pipeline, the result of each command is passed as the last argument to the following command. The output of the final command in the pipeline is the value of the pipeline. See the [Go&nbsp;documentation](https://pkg.go.dev/text/template#hdr-Pipelines) for details.
###### publish
See [build](#build).
###### regular page
Content with the "page" [page kind](#page-kind). See also [section page](#section-page).
###### relative permalink
The host-relative URL of a published resource or a rendered page.
###### render hook
A [template](#template) that overrides standard markdown rendering. See&nbsp;[details](/templates/render-hooks/).
###### remote resource
A file on a remote server, accessible via HTTP or HTTPS with the [`resources.GetRemote`](/functions/resources/getremote) function.
###### resource
Any file consumed by the build process to augment or generate content, structure, behavior, or presentation. For example: images, videos, content snippets, CSS, Sass, JavaScript, and data.
Hugo supports three types of resources: [global](#global-resource), [page](#page-resource), and [remote](#remote-resource)
###### scalar

[`Scratch`]: /methods/page/scratch
[`Store`]: /methods/page/store
[`newScratch`]: /functions/collections/newscratch
###### section
A top-level content directory, or any content directory with an&nbsp;_index.md file. A content directory with an&nbsp;_index.md file is also known as a [branch bundle](/getting-started/glossary/#branch-bundle). Section templates receive one or more page [collections](#collection) in [context](#context). See&nbsp;[details](/content-management/sections/).
###### section page
Content with the "section" [page kind](#page-kind). Typically a listing of [regular pages](#regular-page) and/or [section pages](#section-page) within the current [section](#section). See also [regular page](#regular-page).
###### shortcode
A [template](#template) called from within markdown, taking zero or more [arguments](#argument). See&nbsp;[details](/content-management/shortcodes/).
###### slice
A numbered sequence of elements. Unlike Go's [array](#array) data type, slices are dynamically sized. [Elements](#element) within a slice can be [scalars](#scalar), [arrays](#array), [maps](#map), pages, or other slices. See the [Go&nbsp;documentation](https://go.dev/ref/spec#Slice_types) for details.
###### string
A sequence of bytes. For example, `"What is 6 times 7?"`&nbsp;.
###### taxonomic weight
Defined in front matter and unique to each taxonomy, this [weight](#weight) determines the sort order of page collections contained within a [taxonomy object](#taxonomy-object). See&nbsp;[details](/templates/taxonomy-templates/#assign-weight).
###### taxonomy
A group of related [terms](#term) used to classify content. For example, a "colors" taxonomy might include the terms "red", "green", and "blue". See&nbsp;[details](/content-management/taxonomies/).
###### taxonomy object
A [map](#map) of [terms](#term) and the [weighted pages](#weighted-page) associated with each term.
###### taxonomy page
Content with the "taxonomy" [page kind](#page-kind). Typically a listing of [terms](#term) within a given [taxonomy](#taxonomy).

###### type
See [content type](#content-type).
###### unmarshal
To transform a serialized object into a data structure. For example, transforming a JSON file into a [map](#map) that you can access within a template. See [marshal](#marshal).
###### variable
A user-defined [identifier](#identifier) prefaced with a `$` symbol, representing a value of any data type, initialized or assigned within a [template action](#template-action). For example, `$foo`&nbsp;and&nbsp;`$bar` are variables.
###### walk
To recursively traverse a nested data structure. For example, rendering a multilevel menu.
###### weight
Used to position an element within a collection sorted by weight. Assign weights using non-zero integers. Lighter items float to the top, while heavier items sink to the bottom. Unweighted or zero-weighted elements are placed at the end of the collection. Weights are typically assigned to pages, menu entries, languages, and output formats.
###### weighted page
Contained within a [taxonomy object](#taxonomy-object), a weighted page is a [map](#map) with two elements: a `Page` object, and its [taxonomic weight](#taxonomic-weight) as defined in front matter. Access the elements using the `Page` and `Weight` keys.
