But it does not follow that the English participles
divide time, like the tenses of a verb, and specify the period of action;
on the contrary, it is certain and manifest that they do not.
We have assigned
them a separate place among the parts of speech, because experience has
shown that it is expedient to do so.
OBS. 3.-The English participles are all derived from the root of their
respective verbs, and do not (like those of some other languages) take their
names from the tenses.

Royal Latin and Greek Grammars.]
CLASSES.
English verbs have severally three participles; which
have been very variously denominated, perhaps the most
accurately thus: the Imperfect, the Perfect, and the Plu-
perfect.
