kellertyä

Kellertyä is a Finnish verb form that is not commonly attested in modern standard Finnish. It is sometimes described as a dialectal or archaic variant of kellertää, the verb meaning to become yellow or to take on a yellow hue. In standard usage, kellertää is the preferred form for describing a color change toward yellow, while Kellertyä would refer to the same process in certain dialects or in literary or historical texts.

Etymology and related forms: The form appears to be built from kellertävä, meaning yellowish, and the general pattern of Finnish verbal formation that yields variants with the -yä suffix. Related words include kellertäminen (the act of turning yellow) and kellertävä (yellowish), which help frame Kellertyä within the same semantic field of color change.

Usage and register: Kellertyä is not widely used in contemporary everyday language. When it appears, it is typically in descriptive or poetic contexts, or in regional speech, to convey aging materials, natural color changes, or a yellowing tint. In formal or standard writing, speakers generally use kellertää or more general expressions to describe yellowing.
