-ācea
L. suffix, pl. neut. of -āceus, comp. adj. formative (= -āc- + e-us) = belonging to, of the nature of: see -aceous. The analogy of a few words in L., as gallīnāceus, has been followed in the extensive use of this ending (in neuter pl. agreeing with animālia understood) to form names of classes or orders of animals, like Crustācea crusty or shell-coated animals, Cētācea animals of the nature of the whale (cētus). These are collective plurals; the sing. is supplied by crustaceous animal, crustacean. |
