csoportba

Csoportba is a Hungarian grammatical form, specifically the illative case of the noun csoport meaning "group." It expresses movement into a group or the destination of joining and is used with verbs of entering or joining.

The form is created by adding the illative suffix -ba to the stem csoport. Because the stem contains a back vowel (o) and ends with a consonant, the correct illative is -ba, in accordance with Hungarian vowel harmony. In the plural, the illative would be formed on the plural stem, for example csoportokba meaning "into the groups."

Usage-wise, csoportba is used to indicate being inside or moving into a group. It commonly follows verbs of motion or transition such as belépni (to enter) or beépülni (to join). For example, A diák belépett a csoportba means "The student entered the group." Similarly, Az új tag belépett a csoportba translates as "The new member joined the group." In some contexts, other expressions with a related nuance may use a different suffix (for instance a csoporthoz for “to the group” with certain verbs), but csoportba specifically marks movement into the group.
