The letter in the Spanish alphabet that is silent is the letter H. It is never pronounced except when a word has a C before the H. For example: <em>‘Chaleco’</em> which means ‘waistcoat’.
However, it is helpful in the Spanish alphabet for many reasons, such us marking a hiatus in some words. An example of this case is the word <em>‘búho’ </em>(translation: owl).
it is in correct because you dont need the suffix ben ther for its just yo bailan and you if the word is ellos then it cant be jugabas because that is feminine and ellos is masculine
