sulkeutuisi

Sulkeutuisi is a Finnish verb form that denotes a hypothetical closing action. It is the third-person singular conditional present form of the intransitive verb sulkeutua, which means to close, seal shut, or become closed. The form is used to express what would happen under a given condition, and it is commonly found in conditional clauses introduced by jos or in hypothetical narration.

Usage and meaning: The conditional mood conveys potential or uncertain outcomes rather than actual events. Sulkeutuisi can refer to physical closure, such as a door or lid, as well as more figurative closures, like social withdrawal or a barrier forming in a situation. In practice, it answers questions like “what would happen if…?” and is often found in hypothetical or speculative statements.

Examples:

- Ovi sulkeutuisi, jos sitä kosketettaisiin. (The door would close if it were touched.)

- Hän sulkeutuisi, jos saisisi tarpeeksi tilaa. (He/She would withdraw if given enough space.)

Related forms: Sulkeutuisi is part of a broader Finnish mood system; the present indicative form is sulkeutuu, and other conditional forms exist for different persons (for example minä sulkeutuisin, me sulkeutuisimme). The verb sulkeutua is related to the broader lexical field of closing, sealing, and becoming closed, both in literal and figurative senses.
