Archaic literary word meaning something is clearly apparent or unmistakable. Used in classical or formal written contexts. Antonym: 隠然 (inzen, 'hidden, latent').
Composed of 顕 (ken, 'manifest, display') and 然 (zen, a suffix forming adjectives/adverbs meaning 'like, in the manner of'). The exact historical derivation is uncertain, but it follows a classical Chinese pattern for forming descriptive terms.
