Hyökkäytettiin

Hyökkäytettiin is the past passive perfective form of the Finnish verb "hyökätä," which translates to "to attack" or "to raid." This grammatical form indicates that an action of attacking or raiding has been completed and that the subject of the sentence was the recipient of that action.

In Finnish grammar, the past passive perfective is often used to describe events where the agent of the action is either unknown, unimportant, or implied. For instance, a sentence like "Taloon hyökkäytettiin" would mean "The house was attacked" or "The house was raided." Here, the focus is on the house and the fact that it was subjected to an attack, rather than on who carried out the attack.

This form is distinct from the active past tense, where the subject performs the action. If the sentence were in the active past, it might be "He hyökkäsivät taloon" (They attacked the house). The use of "hyökkäytettiin" shifts the grammatical emphasis.

The construction of "hyökkäytettiin" involves the past passive participle of the verb "hyökätä" combined with the third-person singular form of the auxiliary verb "olla" (to be) in the past tense. However, in many cases, especially in common usage, the auxiliary verb is omitted, and the participle itself functions as the passive past verb. This is a common feature of Finnish passive verb constructions.
