The spelling of the word "doest thoroughly" may seem confusing to some, but it follows traditional Early Modern English rules. The two words are joined together to create the present tense of the verb "do" in the second person singular. The "o" in "doest" is pronounced as /dʊəst/ and the "th" in "thoroughly" is pronounced as /ˈθʌrəli/. When spoken together, the two words create a flowing rhythm with a soft "th" sound. While this spelling may seem outdated, it helps to preserve the historical context of Early Modern English.
"Doest thoroughly" is an old-fashioned and obsolete phrase in modern English that is a variant of "does thoroughly." It is formed by combining the archaic second person singular pronoun "doest" with the adverb "thoroughly." This type of phrasing was commonly used in Early Modern English, particularly during the Elizabethan era.
The term "doest" is the second person singular form of the verb "do," which means to perform or carry out an action. "Thoroughly" is an adverb that denotes the extent or depth to which an action is done. When combined, "doest thoroughly" emphasizes that a particular action is being done completely, exhaustively, and in its entirety.
For instance, if someone were to say, "Thou doest thoroughly investigate the matter," they are expressing that the person addressed is extensively and comprehensively examining the subject under consideration. The phrase implies a careful, meticulous, and rigorous approach to accomplishing the task or action mentioned.
However, it is important to note that this phrase is antiquated and rarely used in contemporary speech or writing. The more common and easy-to-understand formulation in modern English would be "you thoroughly do" or "you do thoroughly."
The phrase "doest thoroughly" is a combination of two separate words: "doest" and "thoroughly". Let's explore the etymology of each word individually:
1. Doest:
The word "doest" is the second person singular form of the verb "do" in Early Modern English. It is derived from the Old English word "duest", which means "you do" or "thou doest". Old English originated from the Germanic language family and was spoken in England between the 5th and 11th centuries. Over time, the form "doest" evolved into the modern "do" used in contemporary English.
2. Thoroughly:
The word "thoroughly" is an adverb derived from the adjective "thorough". The adjective "thorough" originated from the Middle English word "thoruh" or "thuruh".
