An interesting word when it comes to determining the homeland of the Proto-Indo-European language is the English word colt ‘young of horse’. In general no PIE word for ‘colt’ is reconstructed because of the phonetic incoherence of lexical data:
- Germanic: English colt ‘a one-to-four-year-old foal’, Old Norse kult ‘foal, young man’,
- Indo-Iranian: Farsi kurre ‘foal’, Indo-Aryan kišora ‘foal’ (< *kik'eul-),
- Hittite kurka ‘foal’, with Iranian phonetics.
These incoherent words have an Altaic origin as shown by the following potential cognates:
- Mongolian *qulan ‘onager’ Equus hemionus,
- Old Japanese kwoma ‘colt’ < (?) *kul-ma,
