No. The verb you are speaking of is "entender". The third person singular form is "entiende", which is: He/ she/ or You (formal) understnds. To say "they understand", you need the third person plural, which is "entienden".
¿Le entiende / entienden / entiendes / entendéisal español?
Various things:Si (with an accent on the 'i') = 'yes'; without an accent, 'if'.entiende = 'he/she hears/understands' or 'you (formal, singular) understand'.
To understand is either "comprender" or "entender". The terms are interchangeable.
Comprende is the how you would say understand. Also entiende.
Mi familia no entiende
¿Entiende mi español? (Formal) ¿Entiendes mi español? (Informal)
"You understand"..... also often a question..... "You understand?"
Translation: You don't speak or understand Spanish.
bebe, porfavor entiende, yo te amo
"él no entiende" (he doesnt understand) or "él no puede entender" (he can not understand)
(tu) nunca sabes quien entiende el español (add 'tu' for emphasis/clarity)
that doesn't make sense as a sentence exactly, but I believe it's intended to say 'you understand my friend' or 'you understand me, friend.'
