The distinction between languages and dialects is not {{wt|clear-cut}}. A {{wt|lect}} that some regard as a {{wt|dialect}} of a certain language may be regarded as a full, separate {{wt|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 The Languages of David J. Peterson. 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 The Languages of David J. Peterson, 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 [[Project:Languages]]).

For the most part, this page documents cases where The Languages of David J. Peterson’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 The Languages of David J. Peterson 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.<!-- If a three-letter code has been excluded because a two letter code exists, that is not noted.-->

Discussions about splitting, merging, deleting, adding or renaming lects may be archived to '''[[Project: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]].)

Colour coding:
* <code class="ok">gcf</code>: This code is treated as a language. Entries in this language are allowed.
* <code class="not-used">acf</code>: 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 [[Project:List_of_languages/special#Etymology-only_languages|"etymology-only" languages]]).
* <code class="family">ber</code>: This code represents a language family. It is not itself a language, although it may have a [[Project:List_of_languages/special#Not_allowed_in_main_namespace|proto-language]] (<code>ber-pro</code>).
* <code>cmn</code>: The disposition of this code is complex or unclear. See the "Treatment" column.

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

* <code class="not-used">bpw</code> (“Bo”, “Po”, “Sorimi”<!--, “Bo (New Guinea)”, “Bo (Papua New Guinea)”-->) 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 <code>bgl</code> ([[Project:Language treatment/Discussions#Renaming_Bo_.28bgl.29|discussion]]).
* <code class="not-used">bzt</code> (“Brithenig”), a minor constructed language (see {{section link|WT:CFI#Constructed languages}}).
* <code class="not-used">dgu</code> (“Degaru/Dhekaru”), spurious according to ''Ethnologue'' (see [[Wikipedia:Dhekaru|Dhekaru]]); it’s a caste, not a language.
* <code class="not-used">dws</code> (“Dutton World Speedwords”), a minor constructed language (see {{section link|WT:CFI#Constructed languages}}).
* <code class="not-used">ekc</code>, called “Eastern Karnic” by the ISO, is excluded from The Languages of David J. Peterson because it is not clear that there is any data for this “language”, or even that it is a single real language.
* <code class="not-used">ghc</code>, called “Hiberno-Scottish Gaelic” by the ISO, is treated as Irish (<code>ga</code>) or Scottish (<code>gd</code>) according to whether the word in question is from an Irish text, a Scottish one, or both ([[Project:Language treatment/Discussions#Merging_Hiberno-Scottish_Gaelic_into_Irish|discussion]]).
* <code class="not-used">gok</code> (“Gowli”), spurious according to ''Glottolog'' (see [[Wikipedia:Spurious languages|Spurious languages]]); it’s a caste, not a language.
* <code class="not-used">jrt</code> (“Jorto”), spurious ([[The Languages of David J. Peterson_talk:Language_treatment/Discussions#Removing_Jorto,_jrt|discussion]]).
* <code class="not-used">luw</code> (“Luo”<!--, “Luo (Cameroon)”-->), 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 <code>luo</code>.
* <code class="not-used">myi</code> (“Mina (India)”) is excluded because it is spurious. Furthermore, if it were included, a naming conflict would exist with <code>hna</code>.
* <code class="not-used">vms</code> (“Moksela”) is extinct and unattested (see {{w|Moksela language}}).
* <code class="not-used">wai</code> (“Wares”), spurious ([[The Languages of David J. Peterson talk:Language treatment/Discussions#Removing_spurious_Dororo,_Guliguli,_Yarsun,_and_Wares|discussion]]).
* <code class="not-used">wwb</code> (“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.<!--see WP-->
* <code class="not-used">yrs</code> (“Yarsun”), spurious ([[The Languages of David J. Peterson talk:Language treatment/Discussions#Removing_spurious_Dororo,_Guliguli,_Yarsun,_and_Wares|discussion]]).
* <code class="not-used">zba</code> ("Balaibalan"), a minor constructed language ([[Project:Beer_parlour/2020/October#Medefaidrin|brief discussion]]).
* <code class="not-used">zbl</code> (“Blissymbols”, “Blissymbolics”, “Semantography”), a minor constructed language / script (see {{section link|WT:CFI#Constructed languages}}).
* <code class="not-used">zxx</code>, the code for “No linguistic content”.
