What does Ella juega el papel de un personaje en una obra teatral o en una pelicula mean?

Answer 1

She plays the role of a character in a theatrical play or a movie.

NOTE

The word Juega, from the root Jugar means to play, but only in the way a child has fun,. This is not the proper word for "play a role or character" in a play. In Spanish, an actor interprets a character, they don't "play" one. The correct Spanish sentence should read "Ella interpreta el papel de un personaje en una obra teatral o en una película"

The word Juega when referring to an actor playing a role is used quite a bit, but it is a bastardization of Spanish. It is a direct translation of the word Play in English rather than the proper Spanish word. This is known as Spanglish or engañol.

Also the word "play" referring to a theatrical play is "obra", not juega. And the word meaning to play a musical instrument or music is "tocar"
