[208.] The following list shows the principal parts of all the verbs you have had excepting those used in the paradigms. The parts you have had before are given for review, and the perfect participle is the only new form for you to learn. Sometimes one or more of the principal parts are lacking, which means that the verb has no forms based on that stem. A few verbs lack the perfect passive participle but have the future active participle in -ūrus, which appears in the principal parts instead.
