Did you know?

Fulcrum, which means "bedpost" in Latin, comes from the verb fulcire, which means "to prop." When the word fulcrum was first used in the 17th century, it referred to the point on which a lever or similar device (such as the oar of a boat) is supported. The literal use easily supported figurative use, and it didn't take long for the word to develop a meaning referring to one deemed essential to the function or development of something. Despite fulcrum's multiple senses, the word's meanings have kept a steady theme. In zoology, fulcrum refers to a part of an animal that serves as a hinge or support, such as the joint supporting a bird's wing.
