The phrase "didst proud" is an archaic form of language that was used during Shakespearean times. The word "didst" is the second person singular form of the past tense verb "do," meaning "did." The word "proud" means feeling deep pleasure or satisfaction as a result of one's own achievements or qualities. When these two words are combined, "didst proud" means "did with pride." In IPA phonetic transcription, the pronunciation of "didst" is /dɪdst/ and "proud" is /praʊd/.
The phrase "didst proud" is not a stand-alone word with an etymology. However, it is a combination of two words: "didst" and "proud".
The word "didst" is the contracted form of "did" and "st", which was used in Early Modern English as the second-person singular form of the past tense of the verb "do". It was mainly used during the Shakespearean era and is no longer in common use today.
The word "proud" comes from the Old English word "prūd", which originally meant "excellent" or "exalted". Over time, it evolved to its current meaning of feeling a deep satisfaction or pleasure in one's achievements, possessions, or qualities.
Thus, when combined, "didst proud" could potentially mean "you did proudly" or "you accomplished something in a proud manner" in the context of Early Modern English.
