bizottságon
A bizottságon is a Hungarian grammatical case ending, specifically the superessive case with the possessive suffix of the third person singular. In essence, it signifies "on the committee" or "upon the committee" when referring to a singular entity that is possessed by "he," "she," or "it." This case is formed by adding the suffix "-on" to the noun that is the object of the preposition "on" or "upon," and then attaching the possessive suffix "-ja" (which becomes "-a" after certain vowel combinations, and here merges with the "-on" ending to create "-on").
The superessive case in Hungarian is generally used to indicate location on a surface or the position
