"Didst the top your head" is not a recognized phrase or term in the English language, likely due to its incorrect grammatical construction. It appears to be a combination of archaic and modern English words used incorrectly.
The verb "didst" is an outdated form of the auxiliary verb "do," specifically the second-person singular past tense form. It is derived from Old English and was commonly used in Early Modern English, primarily during the Shakespearean era. It means "you did" or "you performed."
"The top" typically refers to the highest part or point of something, like the uppermost portion of an object or a person's head. In the context of the given phrase, it could be interpreted as referring to the crown or peak of one's head.
"To your head" indicates a possession or attachment to someone or something's head. However, the phrase "didst the top your head" does not adhere to standard English grammar rules or idiomatic expressions.
In conclusion, "didst the top your head" does not have a precise definition or meaning in any recognizable English dialect. It seems to be a misapplication or distortion of language, perhaps resulting from a typographical or linguistic error.
