vasilatásában
Vasilatásában is a Hungarian word that translates to "in his/her/its possession" or "in his/her/its ownership" when referring to a singular item or concept. It is the locative case of the possessive suffix "-s", which indicates possession, combined with the demonstrative pronoun "az" (that/the) and the suffix "-ban/-ben" which denotes "in" or "inside." Therefore, "vasilatásában" literally means "in that which is in his/her/its possession."
This grammatical construction is used to indicate that something is currently held, owned, or under the control
The term is relatively formal and less commonly used in casual spoken Hungarian compared to simpler possessive
