LaTeX Font Series

The font series is denoting a combination of the weight (boldness) and the width (amount of expansion).

LaTeX Font Weight and Width Code

The weight and width codes are concatenated to a single series value except that m is dropped unless both weight and width are medium in which case a single m is used.
