Still waters run deep
Suggest a CorrectionMeaning
A quiet or reserved person may have substantial intelligence, feeling, or complexity beneath the surface. Now usually approving, though older examples may warn that quietness conceals danger. Regional use: English proverb with a classical antecedent; now widespread.
Origin
The physical observation that deep rivers can flow quietly is ancient and is found in Latin literature. English reference works date its figurative use to about 1400. Earlier uses could carry a warning that a silent person concealed danger or deceit; modern usage is more often complimentary, suggesting hidden depth. The exact wording varied between still water, still waters, and smooth-running water before the present plural form became standard.
