pysyisi

Pysyisi is a Finnish verb form meaning “would stay” or “would remain.” It is the present conditional form of the verb pysyä, which means to stay or to remain. In Finnish, the conditional mood is used to express hypothetical situations, polite requests, and reported speech.

The form pysyisi belongs to a family of conditional endings that attach to the verb stem pysy-. Personal endings produce a full set: minä pysyisin, sinä pysyisit, hän pysyisi, me pysyisimme, te pysyisitte, he pysyisivät. The bare form pysyisi is commonly the third-person singular form, while all six person/number forms are used in actual language.

Usage and nuance: pysyisi is used to describe what would happen under certain conditions, for example in conditional clauses such as “Jos hän pysyisi täällä, hän voisi auttaa,” meaning “If he would stay here, he could help.” It can also appear in polite or tentative statements and in indirect speech. It is important to distinguish pysyisi from the related verb forma pitiä, which is a different verb meaning “should” or “ought to” in many contexts.

In sum, pysyisi is a key component of Finnish conditional grammar for the verb pysyä, conveying hypothetical or polite meaning and forming part of a broader system of -isi endings that mark person and number in the present conditional.
