Vahvistaisi

Vahvistaisi is the third-person singular conditional mood form of the Finnish verb vahvistaa, meaning to strengthen, confirm, or verify. It is formed from the stem vahvist- plus the conditional suffix -aisi and the third-person singular ending. The corresponding forms for the other persons are: minä vahvistaisin, sinä vahvistaisit, hän vahvistaisi, me vahvistaisimme, te vahvistaisitte, he vahvistaisivat.

Usage in Finnish grammar: The conditional mood expresses hypothetical actions or outcomes and is commonly used in subordinate clauses introduced by jos or kun, or in polite requests and hypothetical assessments. It marks an action that would occur under certain conditions, rather than something asserted as fact.

Examples:

- Hän vahvistaisi tämän tiedon, jos lisätietoja saataisiin.

- Jos tutkimus vahvistaisi väitteen, päätös muuttuisi.

Notes: vahvistaisi, like other -aisi/-äisi forms, reflects modality rather than tense. Its use helps convey possibility, suggestion, or contingency in both written and spoken Finnish.
