Kykeneekö

kykeneekö is a Finnish interrogative verb form meaning "is (he/she/it) able" or "can (he/she/it)". It is the third person singular present tense with the question particle -kö attached to the stem kykene-, derived from the verb kykeneä (also related to the older verb kyetä).

Formation and pronunciation: the form combines the present stem kykene- with the interrogative clitic -kö (harmonized as -kö because of front vowels), yielding kykeneekö. In standard Finnish pronunciation the primary stress falls on the first syllable: [ˈkykeneeko].

Usage: kykeneekö is used to ask whether a third-person subject (including inanimate objects) has the ability, capacity or possibility to perform an action. It appears in direct questions, indirect questions and rhetorical contexts. Example: "Kykeneekö hän suorittamaan tehtävän?" ("Is he/she able to complete the task?"). Negation in questions uses the particle eikö with the verb in negative form: "Eikö hän kykene?" ("Isn't he/she able?").

Related forms include kykenenkö (first person interrogative), kykenevätkö (third person plural interrogative) and alternative colloquial verbs such as pystyä and voida, which often translate to similar meanings (pystyykö, voiko). The choice among these verbs can reflect subtle differences in register, emphasis and aspect.
