pystyisit

Pystyisit is a Finnish verb form meaning "you would be able to" or "could you." It is the second-person singular conditional mood of the verb pystyä, which means "to be able to" or "to have the capacity to." The stem is pysty-, and the conditional ending for the second person is -isit, giving pystyisit. Other persons form with the same stem include minä pystyisin, hän pystyisi, me pystyisimme, te pystyisitte, and he pystyisivät.

Usage of pystyisit is to express hypothetical ability or to make polite requests. It is commonly found in sentences with if-clauses (jos) or in questions formed with the question suffix -ko/-kö. Examples include: Pystyisitkö auttamaan minua tämän kanssa? (Could you help me with this?) and Pystyisitkö tulemaan ajoissa? (Would you be able to come on time?)

Notes on form and nuance: the conditional mood conveys a non-factual, hypothetical scenario or a softer request. In spoken Finnish, the form is widely used to discuss abilities that are not guaranteed or to ask someone to perform an action in a courteous way. The word is closely tied to the verb pystyä and its broader family of conditional forms for different subjects, such as pystyisin (I would be able to) and pystyisi (he/she/it would be able).
