expression
repeatedly; many times; over and over
Emphasizes that an action is done many times or repeatedly. Often used in casual speech.
彼は何遍も同じ話をする。
He tells the same story over and over.
何遍も練習したから、もう完璧だ。
I practiced many times, so it's perfect now.
Similar meaning, but 何度も is more common and neutral in register. 何遍も can sound slightly more colloquial or emphatic.
Also means 'many times', interchangeable in many contexts, but 何遍も may carry a nuance of 'over and over' rather than just a count.
Combination of 何 (what/how many) + 遍 (counter for times) + も (inclusive particle). The counter 遍 is somewhat less common than 回 or 度, giving the phrase a slightly emphatic or colloquial feel.
