Usage

What does nyct- mean? Nyct- is a combining form used like a prefix meaning “night.” It is used in some scientific and medical terms. Nyct- comes from the Greek nýx, meaning “night.” English’s own word night, in fact, shares an ancient root with the Greek nýx. Also related to nýx is the Latin word for nox, source of the combining forms nocti- and noct-. Nyct- is a variant of nycto-, which loses its -o- when combined with words or word elements beginning with vowels. Want to know more?
