The term THEY MAY BE PUCKERED can be solved by the four letter word LIPS. LIPS are a part of the human body located on the face and are used for speaking, eating, and expressing emotion. They are composed of soft tissue and contain nerve endings that allow them to sense touch, pressure, and temperature. Puckering is an action in which the LIPS are pressed together tightly, often in preparation for a kiss or to express disapproval.
