Koondisele
Koondisele is the allative singular form of the Estonian noun koondis. In Estonian grammar, the allative case marks direction toward something, roughly corresponding to the English preposition "to" or "towards." The noun koondis has several senses, including “assembly, group, or unit,” and in historical compounds it is linked to terms referring to concentration camps (for example koonduslaager refers to a camp used for confinement). Therefore, koondisele can be read as “to the assembly” in a general sense or, in historical contexts, as “to the concentration camp,” depending on the surrounding words and referents.
In usage, koondisele appears with verbs of motion or transfer to indicate the destination of an action.
The form is most commonly encountered in linguistic discussions of Estonian grammar or in historical texts
