täydellisellä

Täydellisellä is the adessive singular form of the Finnish adjective täydellinen, meaning "perfect" or "complete." In Finnish, adjectives decline for case, and the adessive singular is used to express manner, state, or location in phrases such as täydellisellä tavalla (in a perfect way), täydellisellä tarkkuudella (with perfect precision), or täydellisellä tasolla (at a perfect level).

Grammatical note: täydellisellä is not a separate lexical item but a grammatical form of täydellinen. The base meaning remains “perfect/complete,” and the adessive form appears before a following noun or as part of a set phrase to indicate manner or degree. It is commonly seen in formal or descriptive contexts.

Usage and nuance: täydellisellä conveys a strong sense of flawlessness or high degree of completeness. It is frequently used in technical, academic, or design-related writing to describe methods, results, or standards that meet an ideal level. Typical collocations include täydellisellä tavalla, täydellisellä tarkkuudella, and täydellisellä tasolla, which translate roughly as “in a perfect way,” “with perfect precision,” and “at a perfect level,” respectively.

Etymology: täydellinen is formed with the root related to fullness, combined with a suffix that creates adjectives meaning “having the quality of.” The adessive form täydellisellä is a standard inflected variant used when the adjective modifies a noun in the adessive case.
