Is English grammar the same in all English-speaking countries?

Answer:
While the core rules of English grammar are largely the same, there are notable variations between different regions, such as American English, British English, Australian English, and others. Differences can include:

• Spelling: (e.g., “color” vs. “colour”).
• Vocabulary: (e.g., “truck” vs. “lorry”).
• Grammar Usage: Certain constructions might be more common in one variant than another (e.g., use of the present perfect tense).
