Use accesskey "n" to jump to the internal navigation links at any point. Skip to the content start.
1 Raw data. Click on the results to see the raw IANA data for a subtag.
2 Find. The description is the name of the subtag, ie. the language, region, etc. You can search on any part of a description (eg. eng gives results that include Bengali, English and Tengwar). Note that some languages may be spelled differently, eg. Panjabi yields three results, but Punjabi only one.
3 Look up. Looks up all forms of all subtags in the list, eg. it returns a language and extlang subtag for cmn. Subtags can be separated by commas, semicolons, hyphens, or spaces, eg. en; fr, ca, Bali-1901.
Only exact matches of subtags are returned, ie. ak doesn't match akk.
If there is no output for a tag, it was not a valid tag in the registry.
4 Check. Looks up all subtags in a language tag (ie. a hyphen-separated list of subtags) and reports problems, if there are any, eg. de-419-DE-alt and ms-cmn.
Warnings are also displayed to guide you in language choices. Example: ms-min-Latn.
If no errors or warnings are reported, the language tag should be ok, though there may be some rare corner cases that are not detected.
5 
provides links from language subtag entries to the SIL Ethnologue. This is useful when trying to find a language. If there is no page for a given language tag, such as nn, click on the result to reveal the full record; if there is a macrolanguage specified, eg. 'no', that will probably yield an ethnologue entry.
6 
provides links from script subtag entries to the most relevant Unicode script block in UniView.
In some cases, there are additional Unicode areas dedicated to the same script. These can usually be easily found alongside the current block in UniView's pull-down control.
Some very large blocks such as Han, Hangul and Egyptian Hieroglyphs are not linked to. Other scripts do not yet have Unicode blocks.
7 Grandfathered tags are pre-RFC 4646 registrations of tags that cannot be completely composed from the subtags in the current registry. If you search for a grandfathered tag it will be displayed in the results, and the subtags that are in the current registry will also be shown.
8 Redundant tags are pre-RFC 4646 registrations of tags that can now be formed by combining separate subtags from the current registry. They do not show up in search results.
9 Extension subtags are not supported in this version of the lookup tool.
BCP 47 language tags are built from subtags in the IANA Subtag Registry. This tool helps you find or look up subtags and check for errors in language tags.
Read Choosing a Language Tag for step-by-step guidelines on creating language tags. This tool also provides information to guide your choices.
lah
Lahnda
lah is a macrolanguage that encompasses the following more specific primary language subtags: hnd hno jat phr pmu pnb skr xhe. If it doesn't break legacy usage for your application, you should use one of these more specific language subtags instead. On the other hand, lah is often preferred by legacy applications rather than pnb (Western Panjabi).This version has been updated to support the approximately 7800 new subtags, including extlang subtags, introduced in July 2009, and the tool now provides help in choosing subtags and a tag checker based on RFC 5646. Please report any bugs to me.
Currently supports the IANA Subtag registry of 2010-06-30. The tool currently reports subtags for 7,843 languages, 225 extlangs, 145 scripts, 296 regions, 46 variants, and 26 grandfathered subtags.
