What does didst mean?
"Didst" is the archaic second-person singular past tense of the verb "do," employed in Early Modern English alongside the pronoun "thou": "thou didst well to come." In that era, English distinguished between a singular and plural form of address — "thou didst" for one person, "you did" or "ye did" for more — much as French still distinguishes tu and vous. Today "didst" survives chiefly in the works of Shakespeare, the King James Bible, and other texts of the sixteenth and seventeenth centuries, as well as in historical fiction, hymnody, and affectionate parody of old-fashioned speech. It carries a distinctly elevated, literary, or ceremonial connotation; no contemporary writer would use it unselfconsciously. For readers encountering older literature, recognizing "didst" — and its present-tense partner "dost" — as simply "did" addressed to one person is essential to following the prose smoothly.

Etymology of didst
"Didst" derives from Old English "dyde," the past tense of the verb "don" (to do), itself from Proto-Germanic *dōną. In Middle and Early Modern English, second-person singular verbs took the ending "-est" or "-st" after "thou," yielding "didst." The same Germanic root gives English cognates such as "deed" and "indeed." The form fell out of everyday use by the late seventeenth century as "thou" gave way to "you."
How didst is actually used
"Didst" belongs to Early Modern English (the language of Shakespeare and the King James Bible) and is now found almost exclusively in literary quotation, religious texts, historical fiction, and playful or ironic imitation of that style. It always pairs with "thou"; using it with any other subject is incorrect. The corresponding modern form is simply "did."
Easily confused with didst
