Tapahtuisi

Tapahtuisi is a Finnish finite verb form of the verb tapahtua, meaning “to happen” or “to occur.” It expresses a hypothetical event or outcome and is used to indicate what would happen under certain conditions. The form represents the conditional mood, typically appearing in clauses introduced by jos (if) or in questions about what would occur.

Formation and usage: Tapahtuisi is the third-person singular conditional form. In Finnish, the conditional mood is formed with the -isi- stem and person endings; tapahtuisi functions as the standard general form for this mood when the subject is not explicitly stated. The form is commonly used in impersonal constructions or when the subject is understood from context.

Examples:

- Mitä tapahtuisi, jos saisit työpaikan? (What would happen if you got the job?)

- Jos se tapahtuisi tänään, olisin iloinen. (If that happened today, I would be happy.)

- Se tapahtuisi, jos kaikki menisi hyvin. (It would happen if everything went well.)

Related terms: The base verb is tapahtua; related forms come from tapahtua in different moods and tenses, such as the present tense tapahtuu/tapahtuu and other conditional forms for different persons. Tapahtuisi is most commonly encountered in hypothetical reasoning and conditional clauses in modern Finnish.
