water's quiet exit strategy, ghosting the liquid world one molecule at a time.
means The process by which a liquid turns into vapor and rises away, molecule by molecule, usually well below its boiling point.
from From Latin 'evaporare' — 'e-' (out) plus 'vapor' (steam, mist), so literally 'to steam out.' That same 'vapor' drifts through English as vapor, vaporize, and even the moody 'vapors' that fainting characters once succumbed to. The word arrived in English in the 16th–17th century, carrying its ancient sense of breath and mist made visible.
