I miss some things in English too:

- Not being able to specify in one word if a friend is a male friend or female friend like amigo/amiga in Spanish.

- The words for friend, boyfriend and girlfriend are too similar. While in spanish amigo/novio, amiga/novia are completely different.

- Not having one word descriptors for someone's ethnicity, as those have to be used very carefully or can't be used in English ag all. Like "Avisale el chelito que la zarca lo está esperando para ir a la tienda del chino" (common in my dialect of Spanish). "Tell the white-person that the light-eyed-person is waiting for him to go to the store owned by the asian-person" (very unnatural in English).
