Common English Slang

Quick Answer: The most common English slang words include cool (good), awesome (great), chill (relax), hang out (spend time together), broke (having no money), my bad (my mistake) and no worries (it's fine). Slang is informal, so use it with friends and in casual messages, never in essays, job interviews or emails to people you don't know. For learners, understanding slang matters more than using it.

Key takeaways

• Safe, all-ages slang: cool, awesome, chill, hang out, grab, broke, no worries, my bad.
• Internet slang such as no cap, sus, slay and low-key is mostly used by younger speakers online. Learn it to understand, use it carefully.
• British and American slang differ: mate, knackered, skint and quid are British; dude, bucks and stoked are typically American.
• Slang is not the same as idioms. Break the ice is an idiom anyone can use; lit is slang tied to age and context.
• In formal situations, swap slang for neutral words: I'm stoked becomes I'm very excited, I'm broke becomes I can't afford it.

Slang vs idioms

Idioms like break the ice or it's raining cats and dogs are fixed expressions with non-literal meanings. They are used across ages and in both casual and semi-formal speech. Slang is more informal and usually changes faster. Learn more in common English idioms and what they mean.

When not to use slang

• Job interviews and formal meetings. Say I'm very excited, not I'm stoked.
• Emails to people you don't know. Thank you, not cheers or thx.
• Exams and essays. IELTS, TOEFL and school essays need neutral or formal language.
• With people you have just met, especially older people or customers.

A common learner mistake is using slang they have heard in films in the wrong situation. For example, writing Hey dude, what's up in an email to a teacher sounds strange and possibly disrespectful.

• Mixing styles. Good afternoon, sir, what's up sounds confusing because it mixes formal and slang.
• Using old slang. Words like groovy now sound old-fashioned or funny.
• Overusing it. One or two slang words can sound natural. Every sentence full of slang sounds forced.
