Why “underthought” is a great word

UNDERTHOUGHT — [Noun] An unexpressed foundational thought that informs a more conscious one. From the English prefix under- (denoting a lower or underlying position) + thought (“mental process”). First attested in 1602 by Ben Jonson. Unlike “subtext,” which is a layer of meaning embedded in a text or conversation, or “ulterior motive,” which implies a calculated aim, an underthought is the personal, often unacknowledged premise from which surface thoughts silently grow. It is the unadmitted doubt that gives confidence its brittle edge, the secret grief that tints a neutral observation, or the buried memory that gives a mundane melody its power to wound—the mind’s private, ongoing dialogue, of which our spoken words are merely the edited transcript.
