"Feicfidh mé na glasraí san ollmhargadh."
Translation:I will see the vegetables in the supermarket.
Is that ment to be a sentence one would say when going to the supermarket confirming that one will find the vegetables as they will be seen?
It’s merely confirming that the speaker will see the vegetables in the supermarket. (The speaker wouldn’t necessarily be going to the supermarket — e.g. they might be seen through one of the supermarket’s windows while the speaker is en route to another destination.)
