See kydde, imperative of kythe (“to show”). Apparently a misunderstanding by Spenser.
- (obsolete, nonce word) knows (second-person singular)
- But, ah! unwise and witlesse Colin Cloute, / That kydst the hidden kindes of many a weede, / Yet kydst not ene to cure thy fore heart-roote, / Whose ranckling wound as yet does rifely bleede.
