The Origin of Comission or Commission

The word commission comes from the Latin word commissio, meaning “an act of entrusting.” It passed through Old French (commission) before entering Middle English. From the beginning, the spelling included double consonants, especially mm and ss.

The confusion exists because English learners often simplify spellings based on pronunciation. When spoken quickly, commission sounds like it has one “m.” Over time, people began writing comission, assuming it was acceptable. However, English never officially adopted this simplified form.

Unlike some English words that changed spelling across regions, commission remained consistent in dictionaries, legal texts, and financial documents.
