How do you use the simple tense verbs?
To use simple tense verbs, simply conjugate the verb according to the subject and tense. In present simple tense, add an 's' for third person singular subjects (he, she, it). In past simple tense, typically add '-ed' for regular verbs or use the irregular form. In future simple tense, use 'will' + base form of the verb. Remember to use the base form of the verb for all other subjects.
