Differences between British and U.S. Spellings

The Internet has made it possible for students in Sydney, Australia, to be taught by a teacher in Fort Lauderdale, Florida. No problem, right? After all, they both speak English. Well, sometimes spelling differences can become an issue. There are many words that are spelled differently in Canada, England, Australia, and other countries that teach “British” English than they are in the United States.

Colour or Color?

When learning to spell, the differences between British. and U.S. English come to the forefront. The following sentence is incorrect in Kansas but correct in Toronto, London, Hong Kong, or Melbourne:

My little sister loves to colour.

British – U.S. Spelling Lists

To accommodate these spelling differences, VocabularySpellingCity had added several lists of British spelling words and their corresponding U.S. spelling words.

These lists can assist teachers and parents who would like to show their students the differences in spelling.

What are the Differences?

Why are there differences? There are many theories from both sides of the Atlantic, but most ascribe the variant spelling to cultural development and different historical experiences. Here are some of these differences:

  • In British English, words that end in -re often end in -er in U.S. English (e.g., theatre; theater).
  • In British English, words that end in -our usually end in -or in U.S. English (e.g., favour; favor).
  • In British English, some nouns that end with -ogue end with -og in U.S. English (e.g., dialogue; dialog).
  • In British English, some nouns that end with -ence are spelled with -ense in U.S. English (e.g., defence; defense).
  • In British English, verbs that can end with either -ize or -ise, always end with -ize in U.S. English (e.g., magnetise; magnetize).
