Phainomenon
Phainomenon is the transliteration of the Ancient Greek φαίνόμενον (phainómenon), meaning “that which appears” or “appearance.” It is the neuter singular participle of the verb φαίνω (phaínō), “to appear, to reveal.” In English, the standard term is phenomenon, but phainomenon is used in scholarly contexts to emphasize the word’s Greek origin and historical usage. The plural in Greek is phainomena.
In philosophy, phainomenon refers to appearances or the way objects are given to perception and experience.
Classical Greek texts use a form of φαίνόμενον simply to mean “that which shines forth” or “appears,”
