Meaning
Two-faced - serving opposite sides at once, or showing one smiling face to each audience while hiding the connection. Less often it is neutral, describing things that genuinely embody two opposing natures at the same time. Usually an accusation of duplicity; in academic prose the neutral two-natures sense survives, so context does the judging. The capital letter is standard. Regional use: General English; Roman origin.
Origin
Janus was the Roman god of beginnings, gates, transitions, and endings - among the most ancient of the pantheon - depicted with two faces because he looks in two directions at once: past and future, war and peace. His epithet Geminus marks the doubling; the month of January is his; and the English word janitor descends, by way of Latin ianitor, from the doorkeeper's staff of the same root. The adjective keeps the god's geometry but adds the human vice: Wiktionary's senses are two-faced, double-faced, deceitful, and, more neutrally, embodying two opposing forces - a philosopher's 2005 phrase for liberalism as both theory and movement, and a critic's 2021 description of an architect who was revolutionary and conservative at once. The deceitful sense needs no citation to be recognized; the god only ever watched both doors honestly.
