Origin of phenomenonLate Latin phaenomenon, from Greek phainomenon, from neuter present participle of phainesthai, to appear; see bhā-1 in Indo-European roots. Usage Note: Phenomenon is the only acceptable singular form of this noun; phenomena is the usual plural. Phenomenons may also be used as the plural in nonscientific writing when the meaning is “extraordinary things, occurrences, or persons”: They were phenomenons in the history of music.
- An observable fact or occurrence or a kind of observable fact or occurrence.
- Appearance; a perceptible aspect of something that is mutable.
- A fact or event considered very unusual, curious, or astonishing by those who witness it.
- A wonderful or very remarkable person or thing.
- (philosophy, chiefly Kantian idealism) An experienced object whose constitution reflects the order and conceptual structure imposed upon it by the human mind (especially by the powers of perception and understanding).
- The universal, common, modern spelling of this term is phenomenon. Of the alternative forms listed above, phaenomenon, phÃ¦nomenon, and phainomenon are etymologically consistent, retaining the Î±Î¹ diphthong from its Ancient Greek etymon Ï†Î±Î¹Î½ÏŒÎ¼ÎµÎ½Î¿Î½ (phainomenon); in the case of the first two, it is in the Romanised form of the Latin ae diphthong, whereas in the latter it is a direct transcription of the original Ancient Greek. The form spelt with Å“ has no etymological basis. All those alternative forms are pronounced identically with phenomenon and are archaic, except for phainomenon, which sees some technical use in academia and is pronounced with an initial fÄ« ([faÉª],).
- By far the most common and universally accepted plural form is the classical phenomena; the Anglicised phenomenons is also sometimes used. The plural form phenomena is frequently misused in the singular. Arising from this misuse, the double plurals phenomenas and phenomenae, as well as a form employing the greengrocerâ€™s apostrophe â€” phenomenaâ€™s â€” are seen in non-standard use; they are erroneous.
From Late Latin phaenomenon (â€œappearanceâ€), from Ancient Greek Ï†Î±Î¹Î½ÏŒÎ¼ÎµÎ½Î¿Î½ (phainomenon, â€œthing appearing to viewâ€), neuter present passive participle of Ï†Î±Î¯Î½Ï‰ (phainÅ, â€œI showâ€).
