If you're asking for the Spanish pronouns, here they are!
-yo (I)
-tú (you, informal)
-él (he)
-ella (she)
-nosotros (as) : we
-vosotros (as) : you, plural, **ONLY USED IN SPAIN**
-usted (you, formal)
-ustedes (you, formal, plural)
-ellos (they, masc.)
-ellas (they, fem)
If I missed anything, sorry~!
Cognates are really simple. they are words that are almost the same in both languages. An example of a true one is: poem- el poema
A false cognate is asistir looks like asist but really it means to attend
How to say in indigenous language name please?
The answer is A because it if you put in a it would say podran
You could choose A and D they mean the same thing. ;)
