Virin vs virino
Hi, just started this course and I was confused about these two words. When used in a sentence, "woman" always translates to "virino" (following the rules about -o at the end of nouns), but when asked to translate just the word "woman" this is given as incorrect, and the answer is "virin". Why do we lose the -o on the end? I know the -in comes from gender but am confused about the ending.
Thanks in advance from a new learner!
