Lesson 2: Navigating Slang & Informal English

Welcome back! In our previous B2 lessons, we looked at advanced vocabulary and idioms. Today, we are looking at how native speakers actually talk outside the classroom.

To sound natural, you must understand informal English and slang. We will cover everyday phrases like hang out and grab a bite. More importantly, we will learn the crucial skill of register matching—knowing exactly when it is appropriate to use slang versus formal language.

Hey Dara, are we still hanging out today?

D

Yeah! I'm driving back from the temple now.

M

Cool. Do you want to grab a bite later?

D

Sure, hit me up when you are ready.

M

warning Watch Out: Register Mismatch!

Slang is only for casual situations.

You must match your language to the situation. Using slang is great with friends, but it is inappropriate to use with your boss or in formal emails.

Register Matching

Register refers to the level of formality in your language. Using slang is a great way to sound natural and friendly when you are with peers. However, a common mistake for English learners is using slang in professional environments.

Always consider your audience before using a phrase like "hit me up." In a business email or when speaking to a manager, you should shift to a formal register and use phrases like "Please contact me."
