What does the word flaccid mean?

According to the Merriam-Webster Unabridged Dictionary of the English Language and other dictionaries like Collins English Dictionary and American Heritage, the word flaccid is an adjective that can be used literally to mean not firm or stiff, or lacking a normal or youthful firmness, or it can be used figuratively to describe someone or something that lacks vigor or force. It can also be used in botany to describe a plant part that is deficient in turgor. If a plant has such turgid leaves, they have been cut and allowed to wilt. Then, sometimes people spread the dead cuttings or bud tissue out on trays or racks of bamboo or canvas and can be rolled for use. This is not done to a healthy plant from planters, only true leaves that are dead. 

The pronunciation of flaccid is ˈflæs-cid. Often, something that is flaccid lacks stiffness or elasticity, like a flaccid penis, flaccid cheeks, or some neurological conditions called a flaccid condition in which one might experience flaccid muscles or flaccid paralysis or numbness. This flaccid flesh could occur from low muscle tone, muscle weakness, polio, infection of the involved muscles, or some other abnormal condition that creates a want of firmness. Trauma could affect the skeletal muscle, respiratory muscles, and somatic nerves as could toxins, bacteria, botulism, or a neurotoxin.
