My cousin (male) needs to go to sleep however instead of using sueno you should use dormir because that is the spanish verb to sleep where as someone would use sueno when saying I have sleep or I am sleepy (tengo sueno)
Maybe you can start by explaining what primo means to you in English?
You can say anything you want to Primo.
The English translation would be "Mi primo tiene once años."
The way you say "Do you need water?" is "Necisita agua?"The c is pronounced as an s and the second i is pronounced as if to say eel.
COUSIN
Roberto es nuestro primo = Roberto is our cousin
Spanish is relatively the same but ricans say gracia w/o the s at the end and primo is cousin so its gracia primo .
primo maggio
primo Juan
hola primo
De tu primo(a)
You can say anything you want to him.
