pyörii

Pyörii is the third-person singular present tense form of the Finnish verb pyöriä. It translates roughly as “he/she/it spins” or “is spinning” and is used to describe something that is turning or rotating around an axis, or something that is circulating.

Origin and morphology: The verb pyöriä means to spin, rotate, or revolve. The form pyörii attaches to a singular subject in present tense. The root is pyör-, related to words such as pyörä (wheel) and kiertää (to turn).

Usage: Pyörii covers physical rotation and circular movement. For example, Maapallo pyörii akselinsa ympäri (The Earth spins on its axis). A single object like a stone can also be described as pyörii on a surface, as in Kivi pyörii pöydällä (The stone spins on the table), though more context may be used to clarify motion.

Figurative use is common as well. The expression ajatus pyörii päässä means that the thought keeps spinning in one’s head or that an idea occupies one’s mind.

Related forms and notes: Pyöriä is the infinitive form; pyöriminen refers to the act or state of spinning, while pyörä means wheel. In Finnish grammar, pyörii is intransitive and agrees with a singular subject, and it can describe both physical rotation and circulating information or thoughts.
