Taittuu

Taittuu is a Finnish verb form meaning "it folds" or "is folding." It is the third-person singular present indicative form of the intransitive verb taittua, which describes the action of bending, folding, or yielding, typically in reference to flexible materials or structures.

Etymology and related forms: Taittua derives from the root taitt- found in the verb taittaa, which means to fold or crease. Related lexical items include taitto, a noun referring to folding or page layout; taittuvuus or taittuvainen to describe something that can be folded or folded easily; and the adjective taittuva, meaning foldable or capable of bending.

Usage: In everyday language, taittuu is used for physical deformation, for example, paper, fabric, or metal that folds or buckles under pressure. Example: Paperi taittuu kuivalla, tasaisella pinnalla. In a figurative sense, it can describe a situation or structure that buckles or yields under stress, as in tekninen rakenne, joka taittuu paineen alla. The term is most common in descriptions of material behavior or mechanical performance.

Technical context: In publishing and printing, the related noun taitto refers to layout or folding of pages, while taittuvuus can describe a material’s foldability. Though related semantically, taittuu itself emphasizes the action of folding rather than the process of arranging or formatting.
