The Origin of Ma’am or Mam

The word ma’am comes from the French phrase ma dame, meaning “my lady.” Over time, English shortened it and added an apostrophe to show missing letters.

• Madam → ma’am

The apostrophe in ma’am is important. It shows that letters have been removed. This makes ma’am a contraction, not a simple word.

The spelling mam developed later as a spoken or regional form. It reflects pronunciation but does not follow the original spelling rule.

This is why ma’am is considered correct in standard English, while mam is not accepted in formal writing.
