en caso que vayas
to say pencil case in spanish you spell it as un estuche
caso cerrado
En todo caso.
Mi estuche tiene. . .
there is not an exact translation for it; it depends on what you want to say. ex: lets go eat - vamos a comer lets jump- saltemos ( as you can see in this case there is no word used instead of lets, but it is understood as lets jump)
"Case" in Spanish is "caso". It is pronounced "KA-so". Please see the Related link below for confirmation of the translation.
You say, "We go to swim." "Vamos a nadar."
ir (to go) con (with)
Vamos Partamos / vámonos / vayámonos
Yeah, I do...lol did you mean, How do you say, you know lots of Spanish? If that's the case, then you say,"Sabes mucho español".
"I go" translates into "yo voy" in spanish.
You can say "¿Puedes salir conmigo?"
