The Difference Between Apologise and Apologize

Depending on where you are in the world, you will need to use either the -ise or -ize ending or suffix as the standard for all words with these endings. This also applies to apologise and apologize. For example, if you use British or Commonwealth English, you should use the -ise ending. However, when it comes to writing for periodicals or documents for international institutions, you may be advised to use -ize. American English always uses the -ize spelling.

  • apologise (British English) - to express repentance or regret for something

  • apologize (American English) - to express repentance or regret for something

Using Apologise and Apologize in a Sentence

Since apologise and apologize have the same meaning, they can be used in the same contexts. The difference ultimately comes down to American vs. British English.

Apologise and Apologize vs. Apologies

The Difference between -ise and -ize Suffixes

The suffixes -ise and -ize mean “cause to become like something else” or “treat like a certain thing.” The -ize ending actually predates the -ise ending. The ending -ise did not become popular until after 1875, but it never became the standard in the United States or in international documents or periodicals.
