British English follows the spellings of words influenced by languages like French and German, while American English simplifies spellings that match pronunciation. For example, “colour” (British) becomes “color” (American), and “flavour” becomes “flavor.”

Pronunciation: Americans emphasize vowels (e.g., tomayto), whereas British emphasize consonants (e.g., tomahto).

Vocabulary: Distinct terms include elevator (US) versus lift (UK).

Grammar:

• Collective Nouns: Americans use singular forms (“The band is playing”), while British allow singular or plural (“The band are playing”).
• Auxiliary Verbs: British use “shall” for future tense; Americans prefer “will” or “should.”
• Present Perfect: British use the present perfect (“I’ve just eaten”), but Americans may use the simple past (“I just ate”).
