In several places, the English name for Qırımtatarca is given as "Crimean Turkish", "Crimean Tatar" is the preferred name in English.
The English Wikipedia page on the language has "Crimean Tatar language" as its title (noting "also called Crimean Turkish"). [[ http://www.ethnologue.com/16/show_language/crh/ | Ethnologue ]] lists "Crimean Tatar" as the main name, as does the [[ http://id.loc.gov/authorities/subjects/sh85034019.html | Library of Congress Subject Headings ]].
Two places it occurs include "Languages" links on English Wikipedia (e.g., on the [[ https://en.wikipedia.org/wiki/Crimean_Tatar_language | Crimean Tatar language ]] enwiki page) where the tooltip for "Qırımtatarca" says "Crimean Turkish", and in the widget that let's you search for languages, where "Crimean" auto-completes to "Crimean Turkish" and "Crimean Tatar" doesn't match anything.
The primary variant name should be "Crimean Tatar" (e.g., on the Qırımtatarca link under "languages") in both those places and elsewhere. It would be nice if both "Crimean Tatar" and "Crimean Turkish" worked in the search widget, but if there can be only one, then "Crimean Tatar" is the one.
