Etymology: The name is built from the genus it belongs to. "Hyaenodon" combines Greek "hyaina", meaning hyena, with "odous" (genitive "odontos"), meaning tooth. The animals were named for teeth that resembled a hyena's, even though they were not closely related to hyenas. Hyenas themselves take their name from the Greek "hyaina", the feminine form of "hys", meaning pig. The ending "-odont" simply means tooth-bearing, as in "mastodont". "Hyaenodont" is a shortened form of "hyaenodontidan", the name of the family built on the same genus, so the two words refer to the same group of animals.
