Borrowed from Old Church Slavonic -ии (-ii), further from Proto-Slavic *-ьjь, whose native descendant *-ей (*-jej) was displaced (compare и́ней (ínej) [ˈinʲɪj] from Proto-Slavic *jьnьjь and пыре́й (pyréj) [pɨˈrʲej] from Proto-Slavic *pyrьjь).

• 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.

Borrowed from Old Church Slavonic -ыи (-yi), displaced expected -ой (-oj) in unstressed positions, from Proto-Slavic *-ъ + *jь,^[1] doublet of -о́й (-ój).

   ‎без- (bez-, “without”) + ‎лик (lik, “face”) + ‎-ий (-ij) → ‎безли́кий (bezlíkij, “faceless”, literally “no-faced”)

• This suffix is a variant of -ый (-yj) used particularly after velars (к г х) due to Russian spelling rules. It is used particularly with two-part compounds, where the second part normally refers to a body part. It does not trigger the Slavic first palatalization.
• These adjectives do have short forms, of accent pattern a.
