Wiktionary:Language treatment

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.

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 conducted at Wiktionary:Language treatment requests (WT:LTR).

List of languages and dialects

Colour coding:

• gcf: This code is treated as a language. Entries in this language are allowed.
• acf: This code is not treated as a separate language. See the "Treatment" column to understand which code should be used instead. In certain cases, these codes may be permitted in etymologies (so-called "etymology-only" languages).
• ber: This code represents a language family. It is not itself a language, although it may have a proto-language (ber-pro).
• cmn: The disposition of this code is complex or unclear. See the "Treatment" column.

Code	Macrolanguage	Subdivisions	Treatment
ak	Akan	fat (Fanti), tw (Twi)	Only the macrolanguage is treated as a language. (discussion)
sq	Albanian	aae (Arbëreshë Albanian), aat (Arvanitika Albanian), aln (Gheg Albanian), als (Tosk Albanian)	Only the macrolanguage is treated as a language. (discussion 1, discussion 2)
gsw	Alemannic	wae (Walser)	Only the macrolanguage is treated as a language. (discussion)
gcf	Antillean Creole	gcf, acf, scf	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) San Miguel Creole French, which is also often considered part of Antillean Creole, is treated as a separate language with the code scf.
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. NOTE: Per 2023, ISO has merged apc (North Levantine Arabic) and ajp (South Levantine Arabic), and it has been requested to do the same here at Wiktionary. There is no conceptual objection to this merger, but it is awaiting resources on the part of the proposers of the merge, as it will take significant effort.
sem-ara	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.

	Mantharta	djl (Jiwarli (macrolanguage code)), dze (Jiwarli (proper)), iin (Thiin), dhr (Tharrgari), wri (Warriyangga)	Jiwarli is treated as a single language with the code djl; the ISO’s split of that code into dze for Jiwarli proper and iin for Thiin has not been followed. However, dhr (Tharrgari) and wri (Warriyangga) have tentatively been retained as languages, rather than being merged, with Jiwarli, into the single language Mantharta. (discussion)

(The code the ISO gave the macrolanguage, yrk, is used for Tundra Nenets.) (discussion) “Yurats” (rts), a barely-attested extinct lect which was probably just a variety of Enets, or a transitional variety between Enets and the Nenets varieties, is excluded for now. (discussion)
ne	Nepali	npi	Only the code ne is used.
	Ngbandi	ngb, deq, ...	deq is not included.
nrf	Norman	roa-nor (Norman), nrf-grn (Guernésiais), nrf-jer (Jèrriais)	Only the macrolanguage Norman is treated as a language, and the code nrf (which the ISO assigned to Guernésiais and Jèrriais) is used for all varieties of it, which had previously been granted separate exceptional codes. Compare fr. (discussion)
no	Norwegian	nb, nn	In practice, both the macrolanguage and its subdivisions are treated as languages. There has been discussion of either treating only the macrolanguage as a language, or of only treating the subdivisions as languages, but there is no consensus about which of these to do. (discussion 1, discussion 2, discussion 3, discussion 4, discussion 5, discussion 6, stalemated vote)
nkt	Nyika	nkt, nkv	Nyika is treated as a single language with the code nkt. The ISO had coded two regional varieties separately, using nkt for the Nyika of Tanzania and nkv for the Nyika of Malawi and Zambia.

Western Persian (pes), Eastern Persian / Dari (prs) and Aimaq (aiq) are subsumed into fa. “Parsi” (prp) and “Parsi-Dari” (prd) are spurious and are excluded. The status of deh and phv is unresolved. (discussion of Tajik, of Judeo-Persian and Bukhari, and of Tat, discussion of pes, prs, aiq, haz, deh and phv)
pih	Pitcairn-Norfolk	cpe-pit (Pitcairn), cpe-nor (Norfolk)	For a time, Wiktionary split Pitcairn-Norfolk into two varieties, granting each an exceptional code: Pitcairn was cpe-pit, Norfolk was cpe-nor. That split has been undone; only pih is now treated as a language. (discussion 1, discussion 2)
pl	Polish	csb (Kashubian), zlw-pom (Pomeranian), zlw-slv (Slovincian)	In practice, both the macrolanguage and its subdivisions are treated as languages, although this has not been discussed.
pua	Purepecha	tsz	Purepecha is treated as a single language with the code pua. The ISO had coded two dialects separately, using pua for “Western Purepecha” and tsz for “Eastern Purepecha”. (discussion)
qu	Quechua	cqu, inb, inj, qub, qud, quf, qug, quh, quk, qul, qup, qur, qus, quw, qux, quy, quz, qva, qvc, qve, qvh, qvi, qvj, qvl, qvm, qvn, qvo, qvp, qvs, qvw, qvz, qwa, qwc, qwh, qws, qxa, qxc, qxh, qxl, qxn, qxo, qxp, qxr, qxt, qxu, qxw, qwe-kch	Only the macrolanguage Quechua (qu), Inga (inb), Jungle Inga (inj), Classical Quechua (qwc) and the standardized variety Kichwa (qwe-kch) are treated as languages. (discussion of Kichwa) NOTE: This is subject to change. There was a recent 2023 discussion about splitting Quechua that ended in a general consensus to split somehow, but no consensus on how to split.
raj	Rajasthani	bgq, gda, gju, hoj, mup, wbr	Not yet discussed.
rom	Romani	rmc, rmf, rml, rmn, rmo (Sinte Romani), rmw, rmy	Only the macrolanguage rom and the subdivision rmo have L2 headers, but all of the subdivisions can have nested lines in translations tables. (discussion)

jya	rGyalrong	sit-sit (Situ), sit-jap (Japhug), sit-tsh (Tshobdun), sit-zbu (Zbu)	Only the subdivisions are treated as languages, the macrolanguage is not. (discussion)
rue	Rusyn	rsk (Pannonian Rusyn)	Rusyn is treated as two separate languages: Carpathian Rusyn (rue) and Pannonian Rusyn (rsk). The ISO originally only had the former code, which was understood to comprise both Rusyn languages. The latter code was approved on 2022. The official designations for these codes are somewhat ambiguous, but are usually understood as rue for Carpathian Rusyn and rsk for Pannonian Rusyn. The English Wiktionary follows this interpretation. (discussion)
rw	Rwanda-Rundi	rn (Rundi proper), haq (Ha, Giha), suj (Shubi), han (Hangaza), vin (Vinza)	Rwanda-Rundi is treated as a single language with the code rw. The ISO had coded the dialects separately, using rw for “(Kinya)rwanda” and rn for “(Ki)rundi”, etc. (discussion)

sel	Selkup	sel-nor (Northern Selkup), sel-sou (Southern Selkup, including Central Selkup)	Northern (sel-nor) and Southern Selkup (sel-sou, including Central Selkup) are treated as separate languages with exceptional language codes. (discussion)
sh	Serbo-Croatian	bs (Bosnian), hr (Croatian), sr (Serbian), cnr (Montenegrin), kjv (Kajkavian)	Only the macrolanguage is treated as a language. (See discussion 1, discussion 2, discussion 3, discussion 4, discussion 5, this discussion from late 2023, more discussion, this old vote, this discussion of kjv, and many other discussions.)
kqu	Seroa	gku	In 2014, the ISO restricted kqu to ǁKuǁe and split off gku ǂUngkue / ǂKunkwe. Wiktionary has not made this split at this time. (discussion)
den	Slavey	scs, xsl	Not yet discussed.
sw	Swahili	sta, swc, swh, bnt-cmw (Chimwiini)	Only the macrolanguage and Chimwiini bnt-cmw are treated as languages. (discussion of sta)

xwk	Wangkumara	xpt (Punthamara), eaa (Karenggapa)	Only the macrolanguage Wangkumara (xwk) is treated as a language, and it is treated as a language, rather than as a dialect of Ngura (which the ISO used to consider a single language with the code nbx).

Excluded codes

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).
• 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”.
