The phrase "turn a nice dime" is a common expression in American English meaning to make a considerable profit quickly. The spelling of the word "dime" is [daɪm] in IPA phonetic transcription, with the "ai" representing the long "i" sound. This word is spelled uniquely compared to other common English words like time or mime, which use the word-final "e" to make the preceding vowel long. The phrase "turn a nice dime" likely originated from the idea of quickly flipping a coin to make a profit.
