Emittoivatko

Emittoivatko is a Finnish grammatical form used to form a yes–no question about past emissions by a plural subject. It combines the past tense verb form emittoivat (they emitted or gave off) with the question particle ko/kö, resulting in emittoivatko, which means “Did they emit?” The word follows standard Finnish word order for questions, placing the verb first and adding the particle at the end.

Morphology and usage notes: In Finnish, the question particle ko/kö attaches to the word it directly follows, and it harmonizes according to the preceding vowel. In emittoivatko, the particle is added to the past plural verb form emittoivat. This construction is common in both written and spoken Finnish when the speaker wants to confirm past emission of something by a group.

Etymology: The verb emittoida derives from emitto-, a stem from the borrowing of Latin emitter, via the concept of sending out or giving off. In Finnish, emittoida is used in contexts such as physics, engineering, biology, or everyday description of glowing, radiating, or releasing substances or signals.

Examples:

- Emittoivatko nämä laitteet valoa? (Did these devices emit light?)

- Emittoivatko reaktiot lämpöä? (Did the reactions emit heat?)
