DID YOU KNOW?
To sublimate is to change the form, but not the essence. Physically speaking, it means to transform solid to vapor; psychologically, it means changing the outlet, or means, of expression from something base and inappropriate to something more positive or acceptable. The word "sublimate" comes from the Latin verb "sublimare," which means "to lift up" or "raise" and which is also the ancestor of our "sublime." "Sublimate" itself once meant "to elevate to a place of dignity or honor" or "to give a more elevated character to," but these meanings are now obsolete.
