Fulcrum -- Noun. 1a. the support about which a lever turns. b. one that supplies capability for action. 2. a part of an animal that serves as a hinge or support. "Adding an adjustable fulcrum to a traditional seesaw, for instance, can teach children about leverage." Kate Sullivan, Press & Sun-Bulletin (Binghampton, New York), August 25, 2017
Did You Know? Fulcrum, a word that means "bedpost" in Latin, derives from the verb fulcire, which means "to prop." When the word first appeared in English in the middle of the 17th century, fulcrum referred to the point on which a lever or similar device (such as the oar of a boat) is supported. It did not take long for the word to develop a figurative sense, referring to something used as a spur or justification to support a certain action. In zoology, fulcrum can also refer to a part of an animal that serves as a hinge or support, such as the joint supporting a bird's wing.
