there's somebody writing wrong, I think they are trying to write "to you"
in spanish sounds similar
Yu is not a wordTu = you
To say "you too" in Spanish, you say "tu tambien".
you already know
Tu lees translates from Spanish to mean you read.
How is your mammy/mummy(assuming 'yu' should be 'tu')
'doy' = 'I give' 'tu' = 'your'.
Kien eres tu tu m markaste
Assuming you mean tu sabes, it means "you know"
Your
Your
tu apellido - your last name
en tu pagina is Spanish for in your page
