Can we remove "a" in this sentence?
What?! The answer was 'we respected her generation' ?!?!?!? There is a problem there!
Here "his/her/your/their" work properly.
Does "seu/sua" mean his/her/your/thier always? Is it just completely context based?
Yes. As it can have more than one meaning, you get it through the context.
I get só confused whenever a word has an "r" like idk if to actually pronounce the r like a Spanish "r". Lol
Seems similar to Spanish, except when:
1) 'r' is the first letter in the word, or
2) they're doubled: 'rr'
in which case it's pronounced like the English 'h'.
When is "dele/dela" ever used? So confused.
dele = his
dela = her
