The spelling of the word "doest again" may seem confusing to many. However, in Old and Middle English, the "st" at the end of verbs indicated a second person singular form (you do, in modern English) and "doest" is a second person singular form of "do". "Doest again" means "do again". In IPA phonetic transcription, "doest" is pronounced as /duːɪst/ with a long "u" sound and the "st" pronounced as a separate consonant sound /st/.
There is no direct dictionary definition for "doest again" as an individual phrase. However, it can be broken down into two separate words: "doest" and "again," each with their own definitions.
"Doest" is an archaic form of the verb "do," specifically used in the second person singular (thou) form of the present tense. It is associated with Early Modern English and Shakespearean language. The term "do" refers to the act of performing or executing an action. Hence, "doest again" implies the repetition or reappearance of an action being done by the second person singular subject, usually in an older or poetic context.
On the other hand, "again" is an adverb primarily denoting the act of returning to a prior state or undertaking an action repeatedly. It implies something that is being done once more or occurring after a previous instance. "Again" is generally used to emphasize the repetition or recurrence of an action or event.
So, "doest again" suggests the act of doing something once more, specifically with the "thou" subject performing the action. The phrase can be seen as an obsolete or literary form meaning "you do it again" or "thou dost repeat."
The phrase "doest again" is a conjugated form of the verb "do" in the second person singular present tense in Early Modern English. "Doest" comes from the Middle English word "doest" which is the second person singular form of "doen", which originates from the Old English word "dōst" or "dest". This form of the verb "do" combines the root "do-" and the second person singular ending "-est".
The root "do-" can be traced back to the Proto-Germanic word "*dō-" which means "to put, to place". It evolved into various Germanic languages, including Old English "dōn" (to do) and Middle English "doen". The second person singular ending "-est" is derived from the Old English "-est" or "-st", which was used to form the present tense verb conjugations for the second person singular.
