TURE XIII.

OF THE AUXILIARY, PASSIVE, AND DEFECTIVE VERBS.

I. AUXILIARY VERBS.

Before you attend to the following additional remarks on the Auxiliary
Verbs, you will do well to read again what is said respecting them in
Lecture XI. page 140. The short account there given, and their
application in conjugating verbs, have already made them quite familiar
to you; and you have undoubtedly observed, that, without their help, we
cannot conjugate any verb in any of the tenses, except the present and
imperfect of the indicative and subjunctive moods, and the present of
the imperative and infinitive. In the formation of all the other tenses,
they are brought into requisition.

are used only in some of the moods and tenses; and when unconnected with
principal verbs, they are conjugated in the following manner:
