| 15Four verbs in this list form their perfect tenses in an unusual way: gaudeō / soleō / cōnfīdō / and one variation of the impersonal verb taedet. None of the 3rd principal parts listed above occurs in the textbook. Instead of using the standard perfect endings + 3rd principal part, these verbs use a participial form + forms of sum. Participle forms change to match the number and gender of the subject of the sentence. Translate them just as you would any other perfect tense verb; do not translate the sum form. These verbs are called semideponent verbs. |
| SAMPLE SEMIDEPONENT VERB |
TRANSLATION |
| (The first form of the participle is masculine and the second feminine. There will obviously be no neuter possibilities for gaudeō since only males and females can rejoice.) |
| gāvīsus / gāvīsa sum |
(I rejoiced) |
| gāvīsus / gāvīsa es |
(you rejoiced) |
| gāvīsus / gāvīsa est |
(he rejoiced / she rejoiced) |
| gāvīsī / gāvīsae sumus |
(we rejoiced) |
| gāvīsī / gāvīsae estis |
(you rejoiced) |
| gāvīsī / gāvīsae sunt |
