The spelling of the word "ARSER IN LE MAIN" may seem confusing, but it is actually based on the French phrase "hors-série en le main", which translates to "special edition in hand". The correct pronunciation of this phrase is [ɔʁs ˈse.ʁi ɑ̃ lə mɛ̃], and the English spelling is simply a phonetic approximation of the French pronunciation. Therefore, the correct spelling of the word in English would be "hors-série en le main", while "ARSER IN LE MAIN" is a simplified version for English speakers.
