pursedlip

Pursedlip is a term used to describe a facial expression produced by pressing the lips together into a tight line, often with the corners of the mouth drawn slightly upward or downward. This tight lip line functions as a nonverbal cue that can accompany other facial cues and body language.

Usage and interpretation: In everyday interaction, pursed lips can signal disapproval, skepticism, hesitation, or concentration. The exact meaning depends on context, intensity, and accompanying cues such as eye gaze, brow movement, and posture. Cultural norms influence how the gesture is interpreted, and it can vary from subtle to pronounced.

Physiology and variation: The expression involves the orbicularis oris muscle and may include minor adjustments around the mouth. It ranges from a faint line to a pronounced squeeze and can occur with partial lip pursing or with tightening of the jaw. The sign can be transient, occurring during moments of doubt, evaluation, or decision-making.

Other contexts: In medicine, pursed-lip breathing is a therapeutic technique used to slow expiration and improve ventilation in conditions such as chronic obstructive pulmonary disease. It uses the same lips-pressed action but serves a physiological purpose rather than a social signal.

Etymology and usage: The term arises from pursing the lips and is used across psychology, linguistics, and popular media to describe a specific facial gesture. It is often described interchangeably with “pursed lips” in discussions of facial expressions.
