Word of the Day:

: a stretching and stiffening especially of the trunk and extremities (as when fatigued and drowsy or after waking from sleep)

"He was coming on to yawn. His breath sucked in the draught from the window. His shoulders hunched, his legs stretched to their toes, he made claws of his fingers in his hands-a fierce pandiculation of his limbs." - Jamie O'Neill, At Swim, Two Boys, 2001

"Carefully orchestrated pandiculations follow a routine: Lips part, the tongue hunkers down, and muscles in the face, mouth and diaphragm engage as the head tilts back." - Laura Sanders, Science News, May 7, 2011

Cat and dog owners who witness daily their pets' methodical body stretching upon awakening might wonder if there is a word to describe their routine-and there is: pandiculation. Pandiculation (which applies to humans too) is the medical term for the stretching and stiffening of the trunk and extremities, often accompanied by yawning, to arouse the body when fatigued or drowsy. The word comes from Latin pandiculatus, the past participle of pandiculari ("to stretch oneself"), and is ultimately derived from pandere, meaning "to spread." Pandere is also the source of expand.
