Questions & Answers about Ég kaupi ekkert nema tómata.
Because the noun is a direct object and needs the accusative plural. With the verb kaupa (“to buy”), objects go in the accusative. The word after nema (“except”) keeps the case it would have as the object:
- Nom. pl.: tómatar (“tomatoes” as the subject)
- Acc. pl.: tómata (“tomatoes” as the object)
- Acc. pl. definite: tómatana (“the tomatoes” as the object)
If you remove the exception phrase, you get the normal object: Ég kaupi tómata.
- With a noun phrase, nema means “except/but.” It does not assign a case; the following noun appears in whatever case the context requires: nema tómata (accusative because it’s the object of kaupi).
- With a full clause, nema means “unless”: for example, Ég kem ekki, nema þú komir (“I won’t come unless you come”). You may also see nema að before clauses.
