Why this word is great
SIDTH — [Noun] Depth or length, especially of something that hangs low, drapes, or trails. From Middle English *sidth*, formed from side (adjective meaning "long, ample, trailing, vast, distant") + the abstract noun-forming suffix -th. Unlike "length" (a neutral, geometric measure) or "depth" (which plumbs a vertical interior), sidth specifies a lateral, suspended expanse—the province of the draped and the pendulous. It is the heavy fall of velvet curtains in a still room, the measured sweep of a king’s ermine-trimmed robe across cold stone, and the weary trail of seaweed left by a retreating wave upon the sand—the melancholy measure of all that is given to gravity.
