How to Talk About Being Late in English: Casual vs. Formal Expressions

Running late happens to everyone. Whether it is an unexpected traffic jam, a delayed train, or simply losing track of time, knowing how to explain your delay politely and naturally is an essential spoken English skill.
​Using the right phrase depends heavily on context. Here is a practical breakdown to help you navigate both professional and casual situations with confidence.
​Formal & Professional Apologies
​Use these phrases when speaking to supervisors, clients, teachers, or in business meetings where maintaining professionalism is key:
​”Sorry I’m late, I got stuck in traffic.” — A classic, universally accepted phrase for commute delays.
​”I apologize for the delay; I was held up in another meeting.” — Ideal when work obligations push back your schedule.
​”Thank you for your patience. I encountered unexpected delays on my way.” — A polite alternative that focuses on thanking the listener rather than over-explaining.
​Casual & Everyday Expressions
​When meeting friends, peers, or attending informal gatherings, keep your tone relaxed and conversational:
​”Sorry I’m late—traffic was crazy!” — A natural, everyday phrase for informal settings.
​”Sorry about that! I completely lost track of time.” — Best used when you were engrossed in a task and forgot the time.
​”So sorry to keep you waiting, I’m pulling up now!” — Perfect for quick text updates when arriving at a meeting spot.
​Essential Vocabulary Breakdown
​To get stuck: To be trapped or unable to move (e.g., “I got stuck in traffic for 20 minutes”).
​Held up: Delayed by an event, task, or obstacle (e.g., “I got held up at the office”).
​Lost track of time: To fail to notice how much time has passed.
