Questions & Answers about Ovatko he sitoutuneita suojelemaan metsiä?
Why is the verb suojella in the -maan form (suojelemaan)?
The word sitoutunut (committed) acts as an adjective of readiness or dedication here. Just like valmis (ready) or kykenevä (capable), it requires the following verb to be in the 3rd infinitive illative (the -maan / -mään form). It essentially means they are committed "into protecting".
Why is the word sitoutuneita in the partitive plural instead of the nominative plural (sitoutuneet)?
Both are grammatically possible, but they carry a slight difference in focus. Using the nominative plural (Ovatko he sitoutuneet...) forms a standard perfect tense verb meaning "Have they committed...". Using the partitive plural (sitoutuneita) treats the participle purely as a descriptive adjective expressing an ongoing state: "Are they committed [people]...".
What is the base form of sitoutuneita, and how is the word constructed?
The base form is sitoutunut, which is the active past participle (often called the NUT-participle) of the verb sitoutua (to commit oneself). To put it in the partitive plural, the -nut ending changes to its stem -ne-, followed by the plural marker -i- and the partitive ending -ta.
Why is metsiä (forests) in the partitive case here? Is it because the action of protecting is incomplete?
