Compounds of essĕ to be.

The following differences from the Simple Verb should be noted:

absum am away, has Pres. Part. absēns, G. absentĭs. So praesum be over, Pres. Part. praesēns, but only in the sense of present.

dēsum am wanting, contracts its e's, as deessĕ pronounced dēssĕ, deeram pronounced dēram.

prōsum am useful, has prōd- where a vowel follows as prōd-est.

possum am able, can is a compound of pŏtĕ (an old Adj. meaning able) and sum. It is conjugated in full below.
