What does SIGMA mean in Scrabble?
noun
The eighteenth letter of the Greek alphabet, written as a capital sigma or a lowercase sigma and final sigma.
Sigma sits between rho and tau in the Greek alphabet and was inherited from an old Phoenician letter, which is part of why English s traces back to it. Outside the alphabet itself, sigma has become a working symbol in mathematics and statistics, where the lowercase letter denotes a standard deviation and the uppercase letter marks a running sum of terms. Physicists also use sigma to label a particular kind of chemical bond formed along the axis joining two atoms. Because of these borrowed technical senses, sigma turns up far more often in science writing than as the ordinary Greek letter it originally was.
