The Origin of Altar or Alter

The two words come from different Latin roots. “Altar” comes from altus, meaning “high.” It describes a raised place for worship and sacrifice. “Alter” comes from alter, meaning “other.” It describes making something different.

The confusion exists because they are homophones. They sound the same but have different spellings and meanings. Only one letter differs, so writers mix them up in writing even though speech is never a problem.

The two words are never interchangeable. “Altar” is only ever a noun. “Alter” is a verb.
