Are you asking how to add the third person +s to the word 'pass'? Quite simple! You add + es. pass --> passes The same goes for any word that ends in a 's' or a similar sound: kiss --> kisses push --> pushes fix - - > fixes I hope that answers your question.

The verb "pass" has several ( more than 1 meaning) Maybe if you use it in a sentence, i could try to explain it better.
