Have you ever heard someone say they "bit off more than they could chew"? Or maybe a coworker described themselves as a "lone wolf"? If you are learning English, expressions like these can be very confusing -- and you will not find them in a dictionary!
These are called idioms -- phrases where the meaning is different from the individual words. Native English speakers use idioms every day, in conversation, at work, and in school. Learning them is one of the best ways to sound more natural and confident in English.
Here are 5 common English idioms and what they really mean.
Meaning: To take on more responsibility or work than you can handle.
Example: "I signed up for four classes and a part-time job. I think I bit off more than I could chew."
This idiom is useful when you want to talk about feeling overwhelmed or overcommitted. You will hear it often in academic and professional settings.
Meaning: Someone who prefers to work or spend time alone rather than in a group.
Example: "He never joins group projects. He is a real lone wolf."
In American culture, being called a lone wolf is not always negative. It can simply mean someone is independent and self-reliant.
Meaning: To remain in one place; to not move.
Example: "The teacher told the students to stay put while she stepped out of the room."
This is a very common phrase in everyday English. You will hear it in casual conversations, instructions, and even in emergency situations.
Meaning: To describe or identify something exactly right; to be completely accurate.
Example: "Your analysis of the problem really hit the nail on the head."
Use this idiom when you want to compliment someone for saying something very accurate or insightful. It is a great expression for academic and professional discussions.
Meaning: To feel sick or unwell.
Example: "I am not coming to class today. I am feeling a little under the weather."
This is one of the most commonly used idioms in American English. Instead of saying "I am sick," many native speakers say they are feeling "under the weather."
