hermaphroditic comes from Hermaphroditus, the son of Hermes and Aphrodite in Greek myth who merged with the nymph Salmacis into one being of both sexes (Greek Hermaphroditos), + -ic. Morphologically, the ending is part of the etymology: the suffix is attached to the older base named in the history, producing a later English derivative. In present English, the adjective sense is "having both male and female reproductive organs", so the historical development ends in a clearly identifiable modern dictionary use. The same base also appears in related forms such as hermaphrodite and hermaphroditism, and in derivatives such as hermaphroditically. Its semantic neighborhood includes bisexual, intersex, androgynous, and monoecious, which helps locate the modern sense without adding a separate etymological claim. The named historical forms include Ancient Greek Ἑρμαφρόδιτος, Ancient Greek Ἑρμῆς, and Ancient Greek Ἀφροδίτη.
