/baɪt ɒf mɔːr ðən juː kən tʃuː/

Dialogue

Sam: "I'm going to train for a marathon, start a new business, and learn Spanish this year."
Emma: "That's ambitious! Aren't you worried you'll burn out?"
Sam: "Maybe a little."
Emma: "Sounds like you're biting off more than you can chew. Start with one goal first!"

Etymology

The idiom comes from the literal act of putting too much food in your mouth at once, making it impossible to chew comfortably. It originated in 19th-century America, when people often chewed tobacco and were offered large plugs — taking too big a piece made chewing difficult. The figurative meaning of overcommitting emerged around the late 1800s and became widespread in the 20th century.

Audience

When to use: Common in everyday informal and formal English to warn or advise someone against overambition or taking on too much. Often used in work, school, or personal goal discussions. It's gentle and cautionary, suitable for conversations, emails, and self-reflection.
