mennessäkin

Mennessäkin is a Finnish postposition that functions similarly to "by" or "even by" in English. It is formed by adding the enclitic particle -kin to the postposition mennessä, which itself derives from the verb mennä (to go). The particle -kin serves to emphasize or add a sense of unexpectedness, much like "even" or "also" in English.

When used, mennessäkin typically indicates a deadline or a point in time by which something is expected to be completed or have occurred. The addition of -kin suggests that this deadline is perhaps sooner than expected, or that it is noteworthy that something will be done by that time. For example, "Huomiseen mennessäkin" could translate to "even by tomorrow," implying that completion by tomorrow is a significant achievement or a surprisingly early deadline.

The grammatical structure involves a noun or pronoun in the genitive case preceding mennessäkin. For instance, "lapsen mennessäkin" might mean "even by the child's (time)," implying a deadline related to the child's age or a specific event involving the child. The meaning is highly context-dependent, and the emphasis provided by -kin can alter the nuance of the statement. It is a relatively common, albeit often subtle, element in Finnish temporal expressions, adding a layer of emphasis to otherwise straightforward time references.
