Can someone help me out? I am not sure how to decline an i-stem 3rd conjugation verb in the present indicative passive for 1st, 2nd, 3rd person singular and plural.

Thank you.

I believe that -i and -e stems work the same on this since Bennett doesn't make any distinction.

Using capere (capi is the stem...i-stem)

Sing. Ind. Pass
1 Capior
2 caperis
3 capitur

Plural
1. capimur
2. capimini
3. capiuntur



The stem keeps the -i except in the active present infinitive, the passive 2nd person singular indicative, the entire imperfect subjunctive, and in the singular imperative, whether active form, or passive (as with deponents).


Co, capite! But cape! Patere, but patimini, etc


So almost always the i remains an i, but for imperfect subjunctive, the "normal" infinitive, and the bizarre singular 2nd person passive indicative and the singular imperative, where i becomes e.
