The Origin of Definately or Definitely

The word definitely comes from the Latin word definitus, meaning clearly defined or certain. It entered English through French in the 16th century.

The spelling includes the word finite, which means having limits. This is why the correct spelling has finite in the middle:
de + finite + ly → definitely

The incorrect spelling definately became common because:

• People pronounce the word quickly
• The middle sounds like nate
• Many writers spell by sound instead of structure

However, definately has never been correct in English dictionaries.
