Learn Finnish: Tämä sääntö koskee vierailijoitammekin. - This rule applies even to our visitors.

The verb koskea has two different meanings depending on the case it governs (its rection). When it means "to concern" or "to apply to" as it does in this sentence, it requires the partitive case (vierailijoita). If the sentence meant "to physically touch," it would require the illative case (vierailijoihin).

Can you break down the suffixes in the long word vierailijoitammekin?

The base word is vierailija (visitor). It breaks down as: vierailijoi- (plural stem) + -ta- (partitive ending, required by koskee) + -mme- (possessive suffix meaning "our") + -kin (clitic meaning "also" or "even").

Is there a strict rule for the order of the possessive suffix (-mme) and the clitic (-kin)?

Yes, a possessive suffix always comes before clitics like -kin (also/even) or -ko/-kö (question particle). The strict order at the end of a noun is: Case ending -> Possessive suffix -> Clitic. This gives us -ta-mme-kin rather than the other way around.

Why does the clitic -kin translate to "even" here instead of "also"?

While -kin translates directly to "also" ("applies also to our visitors"), in English we frequently use "even" to emphasize that a rule covers a surprising or specific additional group. In Finnish, -kin naturally covers both "also" and inclusive "even" in these contexts.
