A Word is a 16 bits unsigned integer value. Its maximal value is 65,535 ((2^16 - 1) or 0xFFFF) and its minimal value is 0.

Nowadays Words are rarely used in arithmetic operations (because most of the CPU have some 32 bit registers, if not 64), but they can be encountered in some API to encode some flags with logical operations (like in a set).
