Possibly akin to Old Armenian Աշնակ (Ašnak, a male given name). Related to شناختن (šenâxtan, “to know, to be acquainted with”).
köken: From the verb tanï- "to know, be familiar with" (compare Old Turkic [script needed] (tanï-, “know, be familiar”), from Proto-Turkic *tanu- (“to know”). Cognate with Bashkir таныш (tanış), Kyrgyz тааныш (taanış), Uzbek tanish (“known, acquainted”), Turkish tanış, etc.

köken: Borrowed from German bekannt (“known, acquainted”), from Middle High German bekant, past participle of bekennen (“to know; to make known”). The verb also developed the sense “to confess” in German, which was separately loaned into Swedish as bekänna. Here the Swedish past participle is bekänd (“confessed”).
familiar (demon supposedly attending and obeying a witch, often said to assume the form of an animal) · hide and seek (game where the players have to hide and one has to seek them out)
köken: Either a loan from Yiddish חבֿר (khaver, “friend, boyfriend”), or a blend of kamraati + toveri. The former of these is now considered more likely. The word is also attested in the sense “companion (in crime)”, so it may have originated in argot.
