Question

Is there any difference between"Ella le gusta comer galletas" and "A ella le gusta comer galletas?" Is adding the A in in the beginning optional? In google translate it keeps translating them into the same

Answer 1

There is no difference it's just how you represent the pronoun itself such as, She likes.
It's opinions ;)

Answer 2

having the a at the beginning is more proper but after all no bid difference honestly.
