Historical Grammar

169. Review the present, imperfect, and future indicative active of regō and audiō, and learn the passive of the same tenses (§§ 490, 491).

a. Observe that the tense signs of the imperfect and future are the same as in the active voice, and that the passive personal endings (§ 164) are added instead of the active ones.

b. Note the slight irregularity in the second person singular present of the third conjugation. There the final -e- of the stem is not changed to -i-, as it is in the active. We therefore have re´geris or re´gere, not re´giris, re´gire.

c. Inflect agō, dīcō, dūcō, mūniō, reperiō, in the present, imperfect, and future indicative, active and passive.
