Should I use "highlight", "high-light", or "high light"?

Highlight as a noun means "the outstanding or remarkable part of an event". It can also mean "a bright part of a picture or image". As a verb it means "to call special attention to".

Highlight is the correct term. "High-light", "high-lights", "high-lighting", and "high-lighted" are always incorrect.

There are some very rare occasions where you might use high light, but only to describe a light that is situated in a high position, e.g. The room was dimly lit by the high light he had placed in the rafters.
