Resembling or relating to New World monkeys, especially in having the characteristics of members of the Cebidae family.
From Cebidae with the suffix -oid meaning 'resembling' or 'like'; from Greek -oeidēs combining form relating to appearance or form.
The -oid suffix is incredibly useful in science because it lets us describe things that have similar features without being exactly the same—like how 'humanoid' means something that looks human-like without actually being human.
