This was a listening exercise for me, I thought the voice said “lingurița“, but fortunately it was accepted. Why do we not use either the definite or the indefinite article, though?
When there is no article, you can usually add an indefinite article and it means the same thing. Not the other way around though.
The difference in cases like this between adding an indefinite article ("o") and not adding one is very small.
Kind of like saying: I have no spoon = Nu am lingurita I don't have a spoon = Nu am o lingurita
Should probably learn it as it is, I don't see it making much sense as a native speaker anyway
Maybe Daverave1212 is suggesting in his second paragraph above that "register" is the defining "difference" as to the inclusion or not of the indefinite article in such quotidian contexts (but it is not actually a matter of grammatical "case"). As he says, it does not make make much sense "anyway"!
Is linguriță a teaspoon as in a unit of measure such as adding a teaspoon of salt to a recipe or a long handled spoon used stirring iced tea?
