For the graphic design term, see Wordmark (graphic identity).

In computer hardware, a word mark, record mark or flag is a bit in each memory location on some variable word length computers (e.g. IBM 705, IBM 1401, IBM 1620) used to mark the end of a word.[1] Sometimes the actual bit used as a wordmark on a given machine is not called wordmark, but has a different name (e.g., flag on the IBM 1620, because on this machine it is multipurpose).[2]
