I did not see your son or something to that effect
that's kinda like slang for "está bien, y tu hijo?" which "he/she is good. and you son?"
you son, your son.
"Quién es el hijo de tu abuelo" is Spanish for "Who is the son of your grandfather?"
the son of your mother and your stepfather
You say, "Soy tu hijo."
I want to have your child.
Tu eres mi hijo.
'You will your son' is not a complete sentence. If you meant,e,g, 'You will (see) your son', it would be '(Veras) a tu hijo'; 'You will (meet) your son' would be '(Encontraras) a tu hijo'
estoy enamorado con tu hijo
Quiero tener tu hijo
This phrase translates to "What is the nickname of your youngest son?" in English.
The cast of Tu hijo - 1935 includes: Claudio Arrau as Pianista Isabelita Blanch as Nanette Mercedes Prendes as Elisa Consuelo Segarra as Tomasa, cocinera
