Genus names of Greek origin

Genus names whose last component is an Ancient Greek noun (or Ancient Greek adjective treated like a noun) obtain their gender from the gender of that noun [Rule 65 (1), Rule 65 (2)]. A list of genus names formed in that manner is provided below, together with the gender of the terminal Ancient Greek noun. For instance, it should be noted that nouns of Greek origin ending in -ma are neuter and declined according to the third declension while Latin nouns ending in -a are usually feminine and belong to the first declension.

Names with Ancient Greek components in other positions are not listed here. The list neither includes names whose last component is a Neolatin word that was strongly modified compared to the original Ancient Greek word from which it was derived, particularly if this modification affected the gender. (Thus bacter, which is masculine, and bacterium, which is neuter, are not listed.) The list includes names with minor modifications, which are shown in parentheses after the Ancient Greek original. See also the LPSN introductory page on forming names.
