Still waters run deep (Prov.)
Meanings
Said of a person who is seemingly quiet and speaks little, but who, in reality, may know a lot and hide a strong and witty personality
Origin
The idiom “still waters run deep” originated in Latin (Q. Curtii Rufi, Historiae Alexandri Magni VII 4,13) as: "Altissima quaeque flumina minimo sono labi" (the deepest rivers flow with the least sound).
This Latin sentence, gave way to the English version in the 1400s, when writers began writing in English, instead of Latin, Greek, or French.
