käsittelisi

Käsittelisi is a Finnish verb form. It is the third-person singular conditional mood of the verb käsitellä, which means to handle, deal with, treat, or process. The dictionary form is käsitellä, and the related noun form is käsittely, meaning handling or processing. The conditional form käsittelisi expresses a hypothetical or contingent action, often translated as “he would handle” or “she would deal with” in English.

Morphology and usage: In Finnish, the conditional mood is formed with the suffix -isi, attached to the verb stem. For the third person singular, the ending is -isi, giving käsittelisi. Other persons have endings such as -isit, -isi, -isimme, -isitte, -isivat. The form is used in subordinate clauses to discuss what someone would do under certain conditions or in polite or tentative statements. It is not the present tense; the present third person singular of käsitellä is käsittelee.

Usage and nuance: Käsittelisi is common in hypothetical statements, negotiations, or discussions about possibilities. It can also appear in polite requests or suggestions framed as conditional possibilities. It contrasts with käsittelee (present) or käsittelisi+että constructions that emphasize potential outcomes rather than definite actions.

Examples:

- Hän käsittelisi tämän asian huolellisesti, jos hänelle annettaisiin lisätietoja. (He would handle this matter carefully if he were given more information.)

- Keskustelussa hän käsittelisi kaikkia näkökulmia. (In the discussion, he would address all viewpoints.)

Related forms: The present tense form is käsittelee (he/she handles). The noun form is käsittely (the act of handling or processing). The verb falls under Finnish verb conjugation patterns for mood and person and is commonly contrasted with the non-conditional present or past forms.
