Principal parts

The principal parts of a verb are the first person singular indicative of the tense-systems occurring in it. These are generally six: the present, future, first aorist, first (or second) perfect active, the perfect middle, and the first (or second) aorist passive. The future middle is given if there is no future active. The second aorist (active or middle) is added if it occurs. Thus:

λῡ́ω loose, λῡ́σω, ἔλῡσα, λέλυκα, λέλυμαι, ἐλύθην.

λείπω leave, λείψω, λέλοιπα, λέλειμμαι, ἐλείφθην, 2 aor. ἔλιπον.

γράφω write, γράψω, ἔγραψα, γέγραφα, γέγραμμαι, 2 aor. pass. ἐγράφην.

σκώπτω jeer, σκώψομαι, ἔσκωψα, ἐσκώφθην.

The principal parts of deponent verbs (356 c) are the present, future, perfect, and aorist indicative. Both first and second aorists are given if they occur.

βούλομαι wish, βουλήσομαι, βεβούλημαι, ἐβουλήθην (passive deponent).

γ́γνομαι become, γενήσομαι, γεγένημαι, 2 aor. ἐγενόμην (middle deponent).
