häviäisivätkin

"häviäisivätkin" is a Finnish word. It is the third-person plural conditional form of the verb "hävitä," which means "to disappear," "to be lost," or "to be defeated." The suffix "-kin" is an enclitic that adds emphasis or a sense of inevitability, often translating to "even" or "indeed." Therefore, "häviäisivätkin" can be translated as "they would indeed disappear," "they would certainly be lost," or "they would indeed be defeated."

This grammatical form expresses a hypothetical or conditional situation in the past or present, suggesting that the disappearance, loss, or defeat is a possibility that is being considered or wished for. It implies a situation where the subject is not currently disappearing, being lost, or being defeated, but under certain conditions, it is a strong likelihood or a desired outcome.

The usage of "häviäisivätkin" often carries a tone of resignation, frustration, or even a slight sense of hope that a negative outcome might occur. It is a nuanced expression that depends heavily on the context in which it is used. For example, it could be used in a sentence like "Toivottavasti nuo ärsyttävät hyttyset häviäisivätkin" which translates to "Hopefully, those annoying mosquitoes would indeed disappear." Here, it expresses a wish for the mosquitoes' disappearance.
