Editing List of ISO 639-2 codes

The '''List of ISO 639-2 codes''' is an index of three-letter language identifiers defined in '''ISO 639-2''' (''Codes for the representation of names of languages — Part 2''). ISO 639-2 is maintained by the ISO 639-2 Language Code Agency (the Library of Congress).

ISO 639-2 includes:
Text about individual languages, macrolanguages, and language collections.
Text about special-purpose codes used when a specific language cannot be identified or is not applicable.
Text about a small set of languages with two alternative ISO 639-2 codes (bibliographic and terminologic).

== Table columns ==
The main table on this page uses the following columns.

ISO 639-2/B is the bibliographic three-letter code (used in some library and cataloguing contexts).
ISO 639-2/T is the terminologic three-letter code (used in some terminology and language-technology contexts).
ISO 639-1 is the two-letter code (only available for a subset of languages).
English name is the English-language label associated with the code in ISO 639-2.
French name is the French-language label associated with the code in ISO 639-2.
Notes contains brief clarifications, including cases where ISO 639-2/B and ISO 639-2/T differ.

=== Notes on B/T code pairs ===
A small number of languages have two ISO 639-2 codes, one bibliographic (B) and one terminologic (T). Both codes refer to the same language entry in ISO 639-2 and are treated as synonyms in that standard.

Common B/T pairs include:
Text listing examples such as French (fre/fra), German (ger/deu), Greek (gre/ell), Icelandic (ice/isl), Armenian (arm/hye), Basque (baq/eus), [[Netherlands|Dutch]] (dut/nld), Romanian (rum/ron), Slovak (slo/slk), Macedonian (mac/mkd), Malay (may/msa), Chinese (chi/zho), Czech (cze/ces), Persian (per/fas).
