The primatological term hominid is easily confused with a number of very similar words:
A hominoid or ape is a member of the superfamily Hominoidea: extant members are the lesser apes (gibbons) and great apes.
A hominine is a member of the subfamily Homininae: gorillas, chimpanzees, humans (excludes orangutans).
A hominin is a member of the tribe Hominini: chimpanzees and humans.
A hominan is a member of the sub-tribe Hominina: modern humans and their extinct relatives.
A human is a member of the genus Homo, of which Homo sapiens sapiens is the only extant subspecies.
In fact, if I can quote the section on “Terminology” from the Hominid article in the New World Encyclopedia, here is what it says:
“The primatological term hominid is easily confused with a number of very similar words:
A hominoid is a member of the superfamily Hominoidea: Extant members are the lesser apes (gibbons) and great apes.
A hominid is commonly a member of the family Hominidae: all of the great apes.
A hominine is a member of the subfamily Homininae: gorillas, chimpanzees, humans (excludes orangutans).
A hominin is a member of the tribe Hominini: Chimpanzees and humans.
A hominan is a member of the sub-tribe Hominina: Humans and their extinct relatives.
A humanoid is a vaguely human-shaped entity.”
Let me emphasize that line that doesn’t appear in the similar quote you posted (maybe it was from a different article?):
“A hominid is commonly a member of the family Hominidae: all of the great apes.”
