Abstract: The decidability of the word problem for the free left distributive law is proved by introducing a structure group which describes the underlying identities. This group is closely connected with Artin's braid group $ {B_\infty }$. Braid colourings associated with free left distributive structures are used to show the existence of a unique ordering on the braids which is compatible with left translation and such that every generator $ {\sigma _i}$ is preponderant over all $ {\sigma _k}$ with $ k > i$. This ordering is a linear ordering.
