VERBS, AUXILIARY. Might = "could"Might, the past tense of may, was originally used in the sense of "was able" or "could." “He was of grete elde and might not travaile.” R. BRUNNE. So
“That mought not be distinguish'd.
i.e. "could not bring himself to allow the winds," &c. It answers to "can" in the following:--
“So loving to my mother,
That he might not beteem the winds of heaven
Visit her face too roughly.
“Ang. Look, what I will not that I cannot do.
Isab. But might you do't, and do the world no wrong?
i.e. "Could you not know."
“Might you not know she would do as she has done?
“I might not this believe
Without the sensible and true avouch
Of mine own eyes.
“But I might see young Cupid's fiery shaft quench'd in the chaste
beams of the wat'ry moon.
i.e. "when he was young enough to be able to play the part of a woman on the stage." Might naturally followed may through the above-mentioned changes. Care must be taken to distinguish between the indicative and the conditional use of might. "How might that be?" (indicative) would mean "How was it possible for that to take place?" On the other hand, "How might that be?" (subjunctive) would mean "How would it be possible hereafter that this should take place?" The same ambiguity still attends "could." Thus "How could I thus forget myself yesterday!" but "How could I atone to-morrow for my forgetfulness yesterday?"
“In that day's feats,
When he might act the woman in the scene,
He proved best man i' the field.
