voimissaan

Voimissaan is a Finnish idiomatic expression formed from the noun voima (power, strength) with the inessive suffix -ssa and a third-person possessive suffix -nsa/ -nsä, yielding a meaning roughly “in his/her/its power.” In everyday language the expression is most commonly used with the verb olla, in the form olla voimissaan, meaning to be in good health, full of energy, or in top form.

The primary sense of voimissaan is physical vitality: a person who feels strong, energetic, or capable is described as voimissaan. The phrase can also convey being in good spirits or peak condition for undertaking an activity. While the literal sense centers on bodily strength, speakers sometimes use it figuratively to indicate readiness, competence, or suitability for a task or challenge.

Common usage patterns include:

- Hän on voimissaan ja jaksaa tehdä töitä. (He is in good shape and can handle the work.)

- Hän sanoi olevansa voimissaan aloittaakseen projektin. (He said he is ready to start the project.)

Grammatically voimissaan is a fixed form that reflects possession and location: the sense of power belongs to the subject described, and the phrase functions adjectivally or adverbially within a sentence.
