Wiktionary:Language treatment

link={{{imglink}}} This is a Wiktionary policy, guideline or common practices page. This is a draft proposal. It is unofficial, and it is unknown whether it is widely accepted by Wiktionary editors.
Policies – Entries: CFI - EL - NORM - NPOV - QUOTE - REDIR - DELETE. Languages: LT - AXX. Others: BLOCK - BOTS - VOTES.
WT:LT redirects here; you may be looking for information on LiquidThreads.

The distinction between languages and dialects is not clear-cut. A lect that some regard as a dialect of a certain language may be regarded as a full, separate language by others. This page contains a list of languages and their (ISO-code-having) dialects, with notes on whether or not the dialects are treated as separate languages on Wiktionary. If there is no note about the status of a particular language+dialect group, the situation is not yet regulated. If multiple dialects are treated as a single language on Wiktionary, but there is no ISO code that represents all of them, the code of one of the dialects is used as the code for the whole language, or an exceptional code is created (for more, see Wiktionary:Languages).

For the most part, this page documents cases where Wiktionary’s treatment of lects deviates from that of the ISO/SIL, e.g. cases where we have merged lects that they have not. Cases where an ISO code has been excluded from Wiktionary altogether (typically because it was too vague to be meaningful) are also documented. Cases where the ISO/SIL itself has merged lects which they formerly granted separate codes, and we have followed suit, are not necessarily documented here.

Discussions about splitting, merging, deleting, adding or renaming lects may be archived to Wiktionary:Language treatment/Discussions (WT:LTD). (Do not start or continue discussions on that page; do that in an appropriate community forum, such as WT:BP or WT:RFM.)

List of languages and dialectsEdit

Code Macrolanguage Subdivisions Treatment
ak Akan fat (Fanti), tw (Twi) Only the macrolanguage is treated as a language. (discussion)

gsw Alemannic wae (Walser) Only the macrolanguage is treated as a language. (discussion)
gcf Antillean Creole gcf, acf Antillean Creole is treated as a single language with the code gcf. The ISO had coded two dialects separately, using acf for “Saint Lucian Creole French” and gcf for “Guadeloupean Creole French”. (discussion)
ar Arabic abh (Tajiki Arabic), abv (Baharna Arabic), acm (Iraqi Arabic), acw (Hijazi Arabic), acx (Omani Arabic), acy (Cypriot Arabic), adf (Dhofari Arabic), aeb (Tunisian Arabic), afb (Gulf Arabic), ajp (South Levantine Arabic), apc (North Levantine Arabic), apd (Sudanese Arabic), arb (Standard Arabic), arq (Algerian Arabic), ars (Najdi Arabic), ary (Moroccan Arabic), arz (Egyptian Arabic), auz (Uzbeki Arabic), ayl (Libyan Arabic), ayn (Yemeni Arabic), ayp (North Mesopotamian Arabic), pga (Juba Arabic), shu (Chadian Arabic), ssh (Shihhi Arabic) Both the macrolanguage and its subdivisions are treated as languages, though not every subdivision with an ISO code or Ethnologue entry is deemed distinct enough for lexicographic division, and the macrolanguage code is used in place of the code (arb) which the ISO gave the standard variety of the language.
Jewish varieties of Arabic, for which there have been introduced some spotty ISO codes (ajt, aju, jye, yhd, yud; jrb), are included within the general regional dialects, or the standard variety, of which the bulk of medieval texts falling under the “Judeo-Arabic” label turn out Hebrew-script forms—as also other sectarian or tribal language forms.
Aramaic arc (Imperial Aramaic), oar (Old Aramaic), aii (Assyrian Neo-Aramaic), aij (Lishanid Noshan), amw (Western Neo-Aramaic), bhn (Bohtan Neo-Aramaic), bjf (Barzani Jewish Neo-Aramaic), cld (Chaldean Neo-Aramaic), hrt (Hértevin), huy (Hulaulá), jpa (Jewish-Palestinian Aramaic), kqd (Koy Sanjaq Surat), lhs (Mlahsô), lsd (Lishana Deni), mid (Modern Mandaic), myz (Classical Mandaic), sam (Samaritan Aramaic), syc (Syriac; Classical Syriac), syn (Senaya), tmr (Jewish Babylonian Aramaic), trg (Lishán Didán), tru (Turoyo), xrm (Armazic) Some varieties are treated as languages, others are not:
The code oar for “Old Aramaic” (up to 700 B.C.E.) is not used; it has been superseded by arc and syc.
“Jewish Babylonian Aramaic” (circa 200–1200 C.E.) is also not allowed L2s, as it has been superseded by arc, but its code tmr is allowed in etymologies.
Assyrian Neo-Aramaic (aii) and Chaldean Neo-Aramaic (cld) are currently treated as languages, as are aij, amw, bhn, bjf, hrt, huy, kqd, lhs, lsd, mid, myz, sam, syn, trg, tru, xrm, and arc and syc. jpa and syr (the latter, “Syriac”, being a macrolanguage covering aii and cld; see discussion) are not currently treated as languages.

Excluded codesEdit

The following ISO 639-3 codes have been excluded without being subsumed into a single other code:

  • bpw (“Bo”, “Po”, “Sorimi”) is excluded for now because its existence as a distinct language is unconfirmed and undocumented, and if it were included, a naming conflict would exist with bgl (discussion).
  • bzt (“Brithenig”), a minor constructed language (see WT:CFI § Constructed languages).
  • cdg (“Chamari”), spurious according to Glottolog (see w:Spurious languages § cdg); it’s a caste, not a language.
  • dgu (“Degaru/Dhekaru”), spurious according to Ethnologue (see w:Dhekaru); it’s a caste, not a language.
  • dws (“Dutton World Speedwords”), a minor constructed language (see WT:CFI § Constructed languages).
  • ekc, called “Eastern Karnic” by the ISO, is excluded from Wiktionary because it is not clear that there is any data for this “language”, or even that it is a single real language.
  • ghc, called “Hiberno-Scottish Gaelic” by the ISO, is treated as Irish (ga) or Scottish (gd) according to whether the word in question is from an Irish text, a Scottish one, or both (discussion).
  • gok (“Gowli”), spurious according to Glottolog (see w:Spurious languages); it’s a caste, not a language.
  • jrt (“Jorto”), spurious (discussion).
  • luw (“Luo”), an unclassified extinct language, is excluded for now because no includable content in it has been put forth, and if it were included, a naming conflict would exist with luo.
  • myi (“Mina (India)”) is excluded because it is spurious. Furthermore, if it were included, a naming conflict would exist with hna.
  • vms (“Moksela”) is extinct and unattested (see Moksela language).
  • wai (“Wares”), spurious (discussion).
  • wwb (“Wakabunga”), an unclassified extinct language, is excluded for now because no includable content in it exists: the only wordlist which was labelled Wakabunga turned out to be Kalkatungu.
  • yrs (“Yarsun”), spurious (discussion).
  • zba ("Balaibalan"), a minor constructed language (brief discussion).
  • zbl (“Blissymbols”, “Blissymbolics”, “Semantography”), a minor constructed language / script (see WT:CFI § Constructed languages).
  • zxx, the code for “No linguistic content”.
