naranja (orange or orange color, this is not to be changed with gender of noun). Naranjo (orange tree). what a PIA (sorry about my idioma) ? there are other examples. la parte is part. El parte is notice. el parto is labor (giving birth). I feel it is a little too late to want to quit.
That's what I thought (because the second Duo introduced it, I do what I do w/ all new words - look it up & add it to my personal study list) but then the answer here is ""Nos gustan esas camisetas naranjas." -- So they HAVE changed it to plural, and that's confusing to me. Are they wrong? What's different that makes this sentence allow something to become plural?
Because with "verbs like gustar", the subject of the sentence goes AFTER the verb not before it. So the actual subject here is camisetas and the verb gustan must agree in number with the subject.
The pronoun before the verb (nosotros) is actually the indirect object, even though it comes first in the sentence. The verb doesn't need to agree with it.
One way to remember this is to think of gustar as "to please". So the sentence in question becomes "Those orange t-shirts please us." The words are still backwards (per English language rules), but it's easier to figure out what corresponds to what in the sentence.
