ithyphallic
Ithyphallic (adj) means relating to the erect phallus symbol carried in ancient processions honouring Bacchus.
Etymology
Borrowed from Late Latin ithyphallicus, from Ancient Greek ἰθυφαλλικός (ithuphallikós), from ῑ̓θῠ́φαλλος (īthŭ́phallos, “phallus carried in festivals of Bacchus; ode sung in honour of the phallus; dance accompanying such an ode; dancer performing such a dance”) + -ῐκός (-ĭkós, suffix forming adjectives meaning ‘of or pertaining to’). ῑ̓θῠ́φαλλος is derived from ἰθῠ́ς (ithŭ́s) (variant of εὐθῠ́ς (euthŭ́s, “straight”)) + φαλλός (phallós, “penis; image of a penis, phallus”). The English word can be analysed as ithyphallus + -ic. As regards the noun, compare Latin ithyphallicum (“poem with the same metre as the hymns to Priapus”).
