The word "wentest" is the second person singular past tense of the verb "go". In IPA phonetic transcription, it is pronounced /ˈwɛntəst/. The "-est" ending indicates that the subject of the sentence is singular and that the action took place in the past. While this form of the verb is not commonly used in modern English, it can still be found in certain contexts, such as in literature or historical texts.
The word "wentest" is an archaic form of the second person singular past tense of the verb "go". It comes from the Old English word "wēntest", which was derived from the past tense of the Old English verb "wenden", meaning "to go" or "to turn". Throughout the evolution of the English language, "wēntest" transformed into "wentest". However, "wentest" is no longer in common usage in modern English, and the standard form today is "you went".
