currently we have two entries: nin and nina.
nin
noun (m)
little boy / male child
nina
noun (f)
1. doll / dolly
2. little girl
I suggest we combine the two and mark the 'little boy / girl' meaning as dialectal.
nin
noun
1. [dial] (m) little boy
2. [dial] (f) little girl
3. [joguina] (f) doll / dolly
and add the following meaning:
4. (f) pupil
I came across the fourth meaning in a book last night and it threw me somewhat as I was only familiar with the first 3 meanings:
...uns ulls verds, amb les nines fosques, partides per una ratlla negra...
"Dark little girls? What? With a black line in the middle? Eh? Sorry? Hmmm, I guess 'nina' must have another meaning"
