Formal vs. Casual Phrases: Speak Like a Pro

English has both formal and casual ways to say the same thing. Knowing when to use each can help you communicate more effectively.
• Casual: I’m busy. → Formal: I am currently occupied.
• Casual: Let me know. → Formal: Please advise.
• Casual: I need more time. → Formal: I require additional time.

Use formal phrases in professional emails, business meetings, and official settings. Casual phrases work best in friendly conversations and informal chats.
