kummallekin

Kummallekin is a Finnish language term used to indicate that something applies to two referenced parties or items. It is a form derived from the determiner kummankin/kumpikin with the enclitic particle -kin, and its exact inflection depends on the syntactic role and the case required by the rest of the sentence. The core meaning is roughly “to both” or “for both.”

In usage, kummallekin appears in contexts where an attribute, action, or proposition concerns two entities that have already been mentioned in the discourse. It is commonly found in both spoken and written Finnish, often in constructions with verbs of suitability, permission, or allocation, and with adjectives or predicates describing shared properties or outcomes.

Examples:

- Kummallekin sopii tämä ratkaisu. (This solution suits both.)

- Kummallekin annettiin mahdollisuus osallistua. (Both were given the opportunity to participate.)

Notes on form and nuance:

- The particle -kin adds emphasis or inclusivity, signaling that both parties or items are being considered or affected.

- The exact form (for example, whether it appears in a dative/allative or another case) depends on the word it accompanies and the sentence structure.

Relation to other terms:

- Kummallekin is closely related to other two-referent terms such as kummankin and molemmat, which also express references to two entities but with different grammatical or emphasis nuances.
