Syntactic actants

Actant 1: whose mouth it is
(a) Genitive
(b) Possessive
Емџ нрђвился большћй рћт Натђши. He liked Natasha's large mouth.
Уголкќ её ртђ гћрестно опџщены. The corners of her mouth were turned down in sorrow.
NB When the word рћт functions as a subject and does not have a descriptive modifier, the construction рћт у + Genitive is often preferred to (a) and (b):
Рћт у Натђши большћй. Natasha has a large mouth.
