tekisivät

"Tekisivät" is the third-person plural, conditional form of the Finnish verb *tehdä*, which means "to do" or "to make." In Finnish grammar, the conditional mood is used to express hypothetical or uncertain actions, often indicating what someone might do under certain conditions. The conditional form conveys politeness, possibility, or hypothetical scenarios rather than certainty.

The verb *tehdä* has an irregular conjugation in Finnish, and its conditional form follows specific patterns. "Tekisivät" is derived from the base form *tehdä* by dropping the infinitive suffix *-ä* and adding the conditional ending *-isivät* for the third-person plural. This form is used when referring to multiple subjects (e.g., they, people) performing an action that is not definitive but suggested, imagined, or politely proposed.

For example, in the sentence *"He tekisivät parhaansa"*, the meaning is "They would do their best," indicating a hypothetical or polite suggestion rather than a definitive statement. This form is commonly used in everyday speech, business communication, and formal writing to soften requests or convey uncertainty.

The conditional mood is distinct from other verb moods in Finnish, such as the imperative (used for commands) or the subjunctive (used for doubts or wishes). While "tekisivät" suggests possibility, it does not carry the same level of certainty as the present or past tense. Understanding its usage helps in constructing grammatically accurate and contextually appropriate Finnish sentences.
