This is the 4th most frequent Dutch word.
is
"Is" in Dutch means "is" in English (third-person singular of "to be").
The word 'is' in this sentence functions as the linking verb, connecting the subject 'Dit' (this) to the complement 'een appel' (an apple), indicating existence or identity.
Dit is een appel.
This is an apple.
Here, 'is' acts as a linking verb between the subject 'Hij' (he) and the adjective 'moe' (tired), describing the state of being of the subject.
Hij is moe.
He is tired.
In this case, 'is' serves as a linking verb, connecting the subject 'De winkel' (the shop) to the predicate adjective 'open,' specifying the current state of the subject.
