| instructive | kostaen | 1) Chiefly in the Soikkola dialect. 2) Chiefly in the Ala-Laukaa dialect. *) For the imperative, the 2nd plural (kostakaa) may be used for the 3rd person as well. **) The interrogative is formed by adding the suffix -k (-ka?/-kä?) to the indicative ***) The deliberative is formed by adding the suffix -k (-ka?/-kä?) or -kse to either the indicative or the potential ****) In folk poetry, a long first infinitive can be formed by adding the suffix -kse-, followed by possessive suffixes, to the first infinitive. Note that sometimes gemination may be undone by this addition. | |||
