Question

Im struggling on this but... How does the 4th Principle part match a sentence in latin

Answer 1

The fourth principal part, as the perfect passive participle, is an adjective.  Usually just the masculine nominative singular is given.  The complete forms are: -us, -a, -um.

N.B.: intransitive verbs do not have a regular 4th principal part (because they can’t be made passive); this includes the verbs that take a dative (noceō, pāreō, etc.)

  Some are listed as –tum/-sum, which is the supine.

 Some have forms in -tūrus/-sūrus (e.g. sum – futūrus; veniō – ventūrus; fugiō – fugitūrus), which is the future active participle

Some have no fourth form: (e.g. timeō – –; noceō —)

Answer 2

Answer:

There are a few different uses for the fourth principle part. It is used to form passive verbs (both indicative and subjunctive)
