kieltääkseen

kieltääkseen is a Finnish word. It is the third infinitive form of the verb "kieltää." The verb "kieltää" means to deny, forbid, refuse, or prohibit. The third infinitive form in Finnish is often used to express purpose, similar to "in order to" or "so that" in English. Therefore, "kieltääkseen" translates to "in order to deny," "in order to forbid," "in order to refuse," or "in order to prohibit," depending on the context.

This grammatical form typically follows another verb or a participle. For instance, one might say "Hän tuli näyttääkseen todisteet" which means "He came in order to show the evidence." Similarly, "He asked for permission kieltääkseen his son's request" would translate to "He asked for permission in order to deny his son's request." The ending "-kseen" indicates the third infinitive with a possessive suffix, which in this case is the third-person possessive suffix, implying that the action of denying or forbidding is being done by the subject of the main clause. This form is crucial for conveying specific nuances of purpose in Finnish sentence structure.
