Questions & Answers about Tutkimusmatkailijat lienevät jääneet tutkimaan haaksirikkoa.
How is the potential perfect formed in the phrase lienevät jääneet?
It uses the potential form of the auxiliary verb olla, which is lienevät for the third-person plural. This is paired with jääneet, the plural past active participle of the main verb jäädä. Together, they express that something probably happened in the past.
Is it common to use this potential perfect structure in everyday speech?
No, the potential mood is quite formal and mostly found in written Finnish or news broadcasts. In everyday spoken Finnish, you would normally express this by using an adverb like varmaan (probably) or ehkä (maybe) alongside the regular perfect tense, for example: ovat varmaan jääneet.
Why is the verb for studying in the form tutkimaan instead of its basic infinitive?
The verb jäädä (to stay or remain) strongly governs the illative case of the third infinitive, which ends in -maan or -mään. When you say someone stays in order to do something, you must use this form rather than the basic dictionary form.
Why does the object haaksirikkoa take the partitive case?
It is in the partitive case because it is the object of the verb tutkia (to study or investigate). Since studying is considered an ongoing, continuous action rather than a completed event with a fixed endpoint, its object must be partitive.
