| -α, | -ας, | -ε, | I, thou, he has ... |
| -αμεν, | -ατε, | -ᾱσι, | we, you, they have ... |
It changes also the σ of the future into a κ—
| τιμήσω— | τετίμηκα | τετίμηκας | τετίμηκε |
| | τετιμήκαμεν | τετιμήκατε | τετιμήκāσι |
but this κ, when the root ends in γ or κ, appears as χ; thus—
| πλέκω | πλέξω | πέπλεχα |
| πράσσω | πράξω | πέπρᾱχα |
and in the same way the final π of the root appears as φ; thus—
| τύπτω | τύψω | τέτυφα |
| γράφω | γράψω | γέγραφα |
In the pluperfect, which is not often used, the same reduplication takes place, and the terminations are—
| -ειν | -εις | -ει |
| -ειμεν | -ειτε | -εισαν or -εσαν |
| as in— |
| | ἐτετύφειν | ἐτετύφεις | ἐτετύφει |
| | ἐτετύφειμεν | ἐτετύφειτε | ἐτετύφεισαν |
