This module exists primarily to provide correct html markup for non-English language text where that text is used in the English Wikipedia.  It has a secondary purpose of providing correct visual rendering for this non-English text.  The module was developed to consolidate processing for {{tlx|lang}}, the {{cl|lang-x_templates|{{tld|lang-??}}}} (most), and {{tlx|transl}} templates into a single source and to use a clearly defined data set extracted from international standards.

The module does not require the myriad {{tld|ISO 639 name ??}} templates, {{tlx|Language with name}}, {{tlx|Language with name and transliteration}}, and {{tlx|transl}}.  It provides error checking and reporting to ensure that the html rendered is correct for browsers and screen readers.

Other templates that get language name support from this module are:
:{{tlx|native name}}
:{{tlx|link language}}

==Data set==
The data set is specified in [[Module:Language/name/data]] and its included data modules:
:;language code-and-name data
::[[Module:Language/data/iana languages]] – from IANA [https://www.iana.org/assignments/language-subtag-registry/language-subtag-registry language-subtag-registry file]
::[[Module:Language/data/ISO 639-3]] – from [http://www-01.sil.org/iso639-3/download.asp sil.org UTF-8 Complete Code Tables Set]
::[[Module:Language/data/wp languages]] – sourcing for the data in this module is unknown
:;language script data
::[[Module:Language/data/iana scripts]] – from IANA language-subtag-registry file
:;language region data
::[[Module:Language/data/iana regions]] – from IANA language-subtag-registry file
:;language variant data
::[[Module:Language/data/iana variants]] – from IANA language-subtag-registry file
:;suppressed-script data
::[[Module:Language/data/iana suppressed scripts]] – from IANA language-subtag-registry file

The data set also includes supplementary data modules:
:;override and other non-standard data
::[[Module:Lang/data]] – For example, when IANA disagrees with ISO 639-3 or when the standard language name is cumbersome or contains information not suitable for use in article space, the <code>override</code> table can hold that language information
::[[Module:Lang/ISO 639 synonyms]] – maps three character ISO 639-2, -2T, -3 codes to two character ISO 639-1 codes – from [https://www.loc.gov/standards/iso639-2/php/English_list.php Codes for the Representation of Names of Languages]

==Error messages and categorization==
Mainspace articles that have errors are placed in appropriate error categories:
:{{cl|lang and lang-xx template errors}}
:{{cl|transl template errors}}

Maintenance categories:
:{{cl|Lang and lang-xx code promoted to ISO 639-1}}
