Sociative case

In grammar, the sociative case is a grammatical case in the Hungarian language which can express the person in whose company (cf.

It is denoted by the suffixes "-stul" and "-stül", depending on vowel harmony. This case is archaic and nowadays the instrumental-comitative case is usually used instead.
