Questions & Answers about Oliko elokuva sekä menestyksekäs että tunteikas?
How do we get menestyksekäs from the noun menestys?
The suffix -käs means "having an abundance of" or an inherent quality of the root noun. Because menestys (success) ends in -s, its stem changes to menestykse- before suffixes are added. Attaching -käs gives us menestyksekäs (successful).
Why is there an -i- in the middle of tunteikas if the root is tunne?
The word tunne (feeling or emotion) forms its plural stem as tuntei-. The suffix -kas is often attached to this plural stem rather than the singular, giving us tunteikas (full of emotion). You will see this plural stem used in other derivations too.
Why are the adjectives menestyksekäs and tunteikas in the nominative case here instead of the partitive?
Adjectives describing a singular, countable subject like elokuva (movie) must be in the nominative case. If the subject were an uncountable mass noun (like weather or music) or a plural noun, you would use the partitive case for the predicative adjectives.
Does että mean "that" or "and" in this sentence?
On its own, että usually means "that". However, the phrase sekä ... että is a fixed pair meaning "both ... and". You cannot replace the että here with ja because it works specifically with sekä to connect the two adjectives.
