The mouth is really important for showing how we feel without talking. It can tell a lot about what someone is thinking or feeling. We use our mouths for showing emotions, eating, breathing, and talking.

The way someone moves their mouth can tell us how they feel or how well they are talking to others. Mouths can be open or closed in different ways to show different feelings. For example, if someone is nervous or shy, they might cover their mouth with their hand. Understanding how the mouth moves is a big part of reading body language.

After the eyes, the mouth is the next thing we look at to understand someone better. Now, let’s learn about what different mouth movements mean.

Nonverbal Communication Of The Mouth

A universal sign of happiness and friendliness, a genuine smile is a powerful way to communicate warmth and approachability. The ‘Duchenne smile,’ characterized by the crinkling of the eyes, is considered the most authentic and engaging type of smile.


I was at a family picnic last weekend, and my little cousin, Jenny, ran up to me with her favorite toy. As she handed it to me, I couldn’t help but break into a big, genuine smile. My eyes squinted a bit, and I felt this warmth inside. Jenny immediately knew I was happy to see her, and she started giggling and gave me a hug. Smiles are like magic; they can make everyone feel so happy and connected!


Lip-biting excitement image

This expression can be a sign of anxiety, stress, or even excitement. People often bite their lips unconsciously when they are deep in thought or nervous about a situation. Or if they like someone or something they see.


Last week, I was waiting for the results of my final exam. I couldn’t help but bite my lower lip while staring at my phone, feeling a mix of excitement and nervousness. It was like a reflex; I didn’t even realize I was doing it until my friend pointed it out. It’s funny how our lips can give away our emotions without us even noticing. Later, when I saw my good grade, I caught myself biting my lip again, but this time it was because I was so happy!”

Pursed lips

Pursed lips can signify disapproval, frustration, or anger. This facial expression is often associated with holding back negative thoughts or emotions. (Think lips together and pressure from the upper lip and bottom.


During a recent meeting at work, my boss was discussing some changes in our project, and I noticed my colleague, Sarah, sitting across from me, purse her lips. It was a subtle but clear sign that she wasn’t happy with the proposed changes. Later, during a break, I asked her about it, and she admitted that she felt frustrated about the direction the project was taking. It’s interesting how something as small as pursed lips can speak volumes about how someone feels, even when they’re trying to hold back their negative thoughts.


Lip Licking Attraction

Licking the lips can indicate anticipation, desire, or nervousness. This action can also be a result of dry lips or a subconscious self-soothing mechanism.


Before going on my first date with someone I really liked, I found myself constantly licking my lips. I couldn’t help it; I was so excited and a bit nervous at the same time.

It’s funny how our body sometimes gives away our feelings, even when we don’t intend to show them.


Covering the mouth with a hand can be a sign of surprise, embarrassment, or an attempt to suppress laughter or other emotions. It can also indicate an effort to hide dishonesty or deceit.

However, in a different situation, during a disagreement with a friend, they stuck their tongue out at me as a sign of defiance, indicating they didn’t agree with what I was saying.
