Depending on what the person is trying to say, usually "hay" means, "there is/there are", and "es" means "is". So you don't need the "es" part of the sentence.
who is she
"is" plural version is "son"
"Es" and "son" mean "is" and "are" in Spanish.
That's bad Spanish; correct Spanish might be something like: "Hay una muchacha, su nombre es Tasha, y ella es muy bonita", meaning "There is a girl, her name is Tasha, and she is very pretty".
"Es lunes" is Spanish for "It's Monday".
Tiempo la hora (Que hora es? = What time is it?)
no = no and es means is
"es' is not a prefix in Spanish.
Es en Espanol. (swiggly line above the n{~}) (It is in Spanish.)
Do you mean "horse"? That is caballo. If you mean "house", that is casa.
is = está or es
"Is", the singular form, is either "está" or "es". In the plural "are", it would be "están" or "son". "There is" or "there are" is denoted by the same word, "hay". Example: "Hay mucha gente en la escuela" - "There are many people in the school". "Hay un carro en la avenida" - ""There is one car in the avenue".
