peitetyllä

Peitetyllä is a Finnish inflected form meaning "on/with the covered" or "at the covered", formed from the past passive participle peitetty (covered) and the adessive case ending -llä. It is not a dictionary headword but a case form used when peitetty modifies a noun and that noun is in the adessive singular.

Formation and grammar: the base verb is peittää ("to cover"); the past passive participle is peitetty. Adding the adessive suffix yields peitetyllä, which expresses location on top of or at something that is covered, or instrumentality/means when translated as "with the covered (something)". The adessive is one of Finnish locative cases and commonly denotes "on" or "at" as well as possession and the means by which an action is performed.

Usage examples:

- Hän istui peitetyllä penkillä. (He/she sat on the covered bench.)

- Lintu oli peitetyllä oksalla. (The bird was on the covered branch.)

- Leikkijä tarttui peitetyllä kädellä. (The player grabbed with the covered hand.)

Variants: plural adessive is peitetyillä; other cases of the participle follow regular adjectival inflection (peitetty, peitetyn, peitettyä, peitettynä, etc.). As an inflected form, peitetyllä appears in sentences where the participial adjective agrees in case and number with the noun it describes.
