Q. Why are such verbs like witnesses on oath?
A. Because they are called “Deponents.”
Of these some few are neuters, as Glorior, I boast.
Cæsar boasted that he came, saw, and overcame. Bald-headed people (like Cæsar) do not, in general, make conquests so easily.
Neuter Verbs ending in or, and verbs deponent, are declined like verbs passive; but with gerunds and supines like verbs active; thus presenting a curious combination of activity and supineness.
There are some verbs which are called verbs personal. A verb personal resembles a mixed group of old maids and young maids, because it has different persons, as Ego irrideo, I quiz. Tu irrides, thou quizzest.
A verb impersonal is like a collection of tombstone angels, or small children; it has not different persons, as tædet, it irketh, oportet, it behoveth.
It irketh to learn Greek and Latin, nevertheless it behoveth to do so.
