Shakespeare’s Macbeth famously says, “If it were done, when ‘tis done, then ‘twere well it were done quickly,” which I rearranged, according to my understanding, as, “‘Twere well it were done quickly, if, when ‘tis done [the assassination], it were done [his ascendancy assured].
I think I’ve understood this line correctly, and if I haven’t, please let me know. But my question otherwise bears on the subjunctive, “‘twere well it were done quickly.” I rather understood this as, “It would be well [or sensible] if it were done quickly.” Have I got that wrong? And did “would” come to replace “‘twere” is these subjunctive constructions?
Thank you for your time!
