Reconstruction:Proto-Slavic/kotiti

Of unknown origin. Similar in meaning to Lithuanian skàsti (“to jump, to move around”), Latvian skatīt (“to check, to look at”), and Latin scateō (“to gush, to spring”) which suggests an origin from a possible Proto-Indo-European *(s)ket- (“to spring, to leap”) (traditionally reconstructed as *skeHt-[1]). Matasović relates it with Irish caith (“to throw”), Old Irish caithid (“to consume”) derived from Proto-Indo-European *keh₂t-.[2]

• Folk etymology (acknowledged by Derksen) relates it to *kotъ (“cat”) +‎ *-iti (a wanderwort of non-native origin), formed in the same way as Proto-Slavic *teliti (“to beget a calf”) < Proto-Slavic *telę (“calf”). However, no particular relationship to begetting of kittens is attested in all languages;
• Vasmer, Trubačev presume generic sense of begetting and consider etymological kinship with Latin catulus (“puppy”). Possibly related to Etymology 1, originally implying “to toss, to throw” → “to spawn”.
