tehokkaalla

Tehokkaalla is a Finnish word form: the adessive singular of the adjective tehokas, meaning "efficient" or "effective". As an adessive, tehokkaalla is used to indicate location ("on", "at"), possession in constructions equivalent to "have" (e.g., minulla on), or instrumentality ("with" or "by means of"). A common approximate pronunciation in plain transcription is "teh-OK-kah-lah".

Linguistic background: tehokas derives from the noun teho ("power, effect") plus the adjectival suffix -kas. The adessive singular ending -lla attaches to the adjective stem to form tehokkaalla. Related forms include tehokkaampi (comparative), tehokkain (superlative) and the adverb tehokkaasti ("efficiently").

Usage examples:

- Tehokkaalla koneella työ valmistui nopeasti. (With an efficient machine the work was finished quickly.)

- Minulla on tehokkaalla tiimillä hyvät edellytykset. (I have good prospects with an efficient team.)

The form is grammatical and context-dependent rather than lexicalized; its meaning follows regular Finnish case and adjective agreement patterns. Synonyms for the base adjective tehokas include toimiva and tehokas in broader contexts, while nuances are often expressed through word order, case choice, or additional modifiers.
