kummasta

Kummasta is a Finnish interrogative form used to ask about choice or selection among two or more items. It functions as part of the question that translates roughly to "from which (one)?" and is most commonly encountered in sentences that present alternatives.

In standard Finnish, kummasta is typically used with a noun that denotes the items being compared, often in the partitive or genitive case, and with a following verb that indicates preference or selection. For example, in a context comparing two beverages, one might ask, “Kummasta kahvista pidät?” meaning “Which of the two coffees do you prefer?” The form can also appear in short, elliptical questions where the options are understood from context, such as simply “Kummasta?” in a setting where two choices have been presented.

Etymology and relation to other forms: kummasta is related to the broader family of interrogative forms that express “which,” including kumpi and kumpa. These forms share the function of distinguishing between two or more items, but kummasta specifically marks the source or origin of the choice in question.
