"Sé que mi español es malo pero me entiendes"
Mal
Comprende is the how you would say understand. Also entiende.
I'm bad = soy malo
No entiendes esto?
no lo entenderías
There are two ways that you can say "too bad" in Spanish, lástima or ¡qué pena!
"él no entiende" (he doesnt understand) or "él no puede entender" (he can not understand)
Dog is 'perro' and bad is 'malo' so I guess 'perro malo' or maybe 'malo perro'. A computer translator gave me 'mún perro' but either I don't understand enough Spanish or that's not right.
"Mal" in Spanish means "bad". In Spanish it is pronounced "mahl".
Culpa mía.
