Webster's Revised Unabridged Dictionary
    • Radical sign (Math) the sign √ (originally the letter r, the initial of radix, root), placed before any quantity, denoting that its root is to be extracted; thus, √a, or √(a + b). To indicate any other than the square root, a corresponding figure is placed over the sign; thus, ∛a, indicates the third or cube root of a.
