    Why Do UK and US English Differ?

    However, American English spellings are mainly determined by how words are pronounced.

    8 Spelling Differences in British & American English

    Most of the time, British and Americans understand each other. However, there are still a few significant differences between UK and US English, which can lead to confusion and misunderstandings. Following are eight main spelling differences between UK and US English.

    -Ae- Vs -E- and -Oe- Vs -E-

    British English words which were derived from the Ancient Greek, have the double vowels -ae- or -oe-, while the American English words are just spelled with an -e-. Most of these words are technical or medical terms

    • Anaemia vs Anemia
    • Leukaemia vs Leukemia
    • Diarrhoea vs Diarrhea

    -Our Vs -Or

    This is one of the classic differences between British and American English spellings resulting from the French influence. All British words ending in -our are spelled with -or- in American English.

    • Behaviour vs Behavior
    • Colour vs Color
    • Flavour vs Flavor

    -Ence Vs -Ense

    Nouns that end with -ence are used by British English, while American English prefers the spelling with -ense at the end.

    • Defence vs defense
    • Offence vs Offense
    • Pretence vs Pretense

    -Re Vs -Er

    Similar to words ending in -our, words spelled with -re at the end originated from French spellings, which are accepted in UK English. However, the Americans replace the -re with -er to better reflect the pronunciation.

    • Fibre vs Fiber
    • Centre vs Center
    • Metre vs Meter

    Words Ending in “l”

    Some verbs ending in “l” have the “l” in British English doubled before adding a suffix or ending. However, the American spellings don’t double the “l” in any case.

    • Travelled vs Traveled
    • Fuelling vs Fueling

    Words Ending in –E

    Words ending with a silent -e in both American and British English are stemmed from Old English. US English prefers to drop the silent -e while UK English prefers to keep it.

    Also, there are words with an -e at the end derived from French loanwords where the consonant before the final -e is doubled. The British words retain the -e at the end, while Americans tend to omit the consonant and the final -e from the spellings.

    • Glycerine vs Glycerin
    • Annexe vs Annex
    • Gramme vs Gram
    • Programme vs program

    -Ize Vs -Ise

    Some verbs in British English can be spelled with either -ize or -ise at the end. However, they are always spelled with -ize in American English.

    • Apologise vs Apologize
    • Recognise vs Recognize
    • Organise vs Organize

    -Yse Vs -Yze

    Words ending in -yse are only acceptable in UK English, while the US English words are always spelled with -yze.

    • Paralyse vs. Paralyze
    • Analyse vs. Analyze
    • Catalyse vs. Catalyze
