An alternative term for a Binomial Coefficient, in which ${n\choose k}$ is read as ``$n$ choose $k$.'' R. K. Guy suggested this pronunciation around 1950, when the notations ${}^nC_r$ and ${}_nC_r$ were commonly used. Leo Moser liked the pronunciation and he and others spread it around. It got the final seal of approval from Donald Knuth when he incorporated it into the mathematical typesetting language as $\{{\tt n}\backslash{\tt choose\ k}\}$.
