Question

if the adjectives ends with the letter "e" just add "r"​

Answer 1

Respuesta:

If an adjective ends with the letter 'e' like wide, you don't have to add 'r'. You can add 'r' to the adjective when you want to say or write a sentence like this: the book is wider than the notebook (traduccion : el libro es mas amplio que la libreta)

Explicación:

when you like to say (for example) ''a wide book'' you don't have to add anything, only you have to add 'r' when you would like to say or to write a comparative sentence like ''the book is wider than the notebook''

additional information:

when you want to write or to say comparative sentences, if the adjective is short (like ''wide'') you have to add 'r' (wider), but when the adjective is long (like ''expensive'') you have to add 'more' (more expensive)
