Apologised or Apologized: Quick Answer

Both spellings are correct, but they are used in different varieties of English.

Origin:

The verb apologize comes from the Greek word apologia, meaning a speech in defense.
Over time, the word passed through Latin and French before entering English.

When English split into regional varieties, spelling rules changed:

• British English kept -ise
• American English simplified it to -ize

That’s why both apologised and apologized exist today, with the same meaning but different spellings.

Grammar Insight: Why -ise and -ize Both Exist

Many people believe -ize is American and -ise is British, but the truth is more nuanced.

• -ize comes from Greek via Latin
• British English accepts both -ise and -ize, but -ise is more common
• American English uses -ize almost exclusively

That’s why apologised dominates UK writing, while apologized dominates US writing.
