[I. Primitive Verbs.]
[922.] Root verbs have their principal parts as follows:
| sum, am | esse | —— | —— |
| ——, become, get, am | fore | fuī | —— |
For fuam, &c., forem, &c., fore, see [750]. fuī, &c., serves as the perfect system of sum.
| pos-sum, can | pos-se | —— | —— |
| ——, can | —— | potuī | —— |
potuī, &c., serves as the perfect system of possum. Of the present system of potuī, only potēns, powerful, is used, and only as an adjective.
| dō, give, put | dare | dedī | datus |
