* This suffix is added particularly to animate nouns, and has the special possessive declension. It triggers the Slavic first palatalization but not (normally) iotation; but see ребя́чий (rebjáčij) from ребя́та (rebjáta), with iotation.
* If added to reducible nouns, the noun assumes the unreduced form.
