Kiertämis

Kiertämis is a Finnish combining form and noun stem used to denote the act or process of turning or rotating. In everyday Finnish the standard gerund kiertäminen is common, but kiertämis appears especially in technical language as the base for compound nouns describing turning-related processes or properties.

Etymology and form: kiertämis is derived from the verb kiertää, meaning to turn, circle, or revolve. As a combining form it functions similarly to turning or rotation in technical terminology, allowing speakers to create specialized nouns such as kiertämisprosessi (the turning process) or kiertämisnopeus (the speed of turning).

Usage and contexts: The kiertämis form is typical in engineering, physics, and other technical domains where precise terminology is required. It often appears in compound nouns that specify aspects of rotational motion, gear systems, or circular dynamics. In general Finnish prose, kiertäminen remains the preferred form for ordinary narration, while kiertämis- compounds are common in manuals, specifications, and design documents.

Relation to kiertäminen: Kiertämis is not usually used as a standalone noun in normal speech; instead it serves as a stem in compounds. Its use depends on style guides and the need for concise, technical expression. When clarity is paramount for non-specialists, kiertäminen may be preferable, whereas kiertämis- compounds convey precise technical meaning.
