I69 The Conditional Mood of Auxiliary Verbs.
The Auxiliary Verbs have only the Indicative
form of the Subjunctive; they do not use the
" shall-form." For example, we do not say, " If I
should can (be able to) come, I should will (wish to)
do so," but "If I could come, I would do so."
Remembering that" could,"" might," and " would"
are the Past Tenses of "can," "may," and "will,"
and also bearing in mind the meanings of " can,"
"will," &c., viz. " to be able," " to be willing,"
we shall be able to express their Indicative Subjunctive forms in the ordinary Subjunctive forms,
as follows:
1 The form "if he see " is now nearly extinct in good modern
English. But a remnant of it renmais in " if it were," which is the
only correct mo(lern form for the Past Conditional. " If I was you "
is ungranmmatical, though found (as well as "you was") il the
eighteenth century. " If it be," " though it be," are also still used,
though falling into disuse. " Were " generally implies a Condition
not fulfilled
