mightest
Archaic second-person could
Mightest is an archaic second-person singular past tense form of the verb "may," used with "thou" in Early Modern English.
It expressed possibility or permission: Thou mightest have warned me.
The form appears primarily in the King James Bible, Shakespeare, and other texts from the 16th and 17th centuries.
Modern English has collapsed all past tense forms of "may" into the single word "might."
