Questions & Answers about Opiskelijat kävivät ostamassa lounasta ruokarekasta.
Why is the verb for buying in the form ostamassa instead of ostamaan?
The verb käydä (to visit, or to go and come back) requires the 3rd infinitive to be in the inessive case (-massa or -mässä). This is because käydä acts like a static location verb grammatically. If the sentence used mennä (to go), it would take the illative case instead (menivät ostamaan).
What is the exact difference in meaning between kävivät ostamassa and menivät ostamaan?
Kävivät ostamassa implies a completed round trip: the students went to the food truck, bought lunch, and have already returned or moved on. Menivät ostamaan only focuses on the departure and does not necessarily imply they have come back yet.
Why is the word for lunch (lounas) in the partitive case (lounasta)?
In this context, lunch is being treated as an uncountable substance or an unspecified amount (meaning they bought 'some lunch'). If they were buying one specific, complete lunch portion, it would take the accusative case, which looks like the genitive (lounaan).
Why does the sentence use ruokarekasta (from the food truck) instead of a location case like ruokarekalla (at the food truck)?
