The document discusses verb tenses and forms in English. It describes 6 tenses - present, past, future, present perfect, past perfect, and future perfect - and explains how they indicate the time of the verb's action. It also distinguishes between regular and irregular verbs. Regular verbs form their past tense and past participle by adding "-ed" or "-d", while irregular verbs do not follow a set pattern.
