Questions & Answers about ¿Te duele el estómago? Casi nunca.
Why is casi nunca just standing alone here without a verb?
In conversation, adverbs of frequency like casi nunca (almost never) can be used as short answers all on their own. If you wanted to answer with a full sentence, you would say Casi nunca me duele (It almost never hurts me). Notice that when casi nunca comes before the verb, you don't need to add a double negative!
Why do we use te duele here instead of just asking duele?
Why does it say el estómago (the stomach) instead of tu estómago (your stomach)?
In Spanish, when talking about body parts, you almost always use the definite article (el, la, los, las) instead of a possessive word like tu or mi. Because we already used the pronoun te (to you) earlier in the sentence, it is perfectly clear whose stomach we are talking about!
The verb is doler, so why is it spelled duele here?
