Abstract
A theory of basic commutators is developed here which applies to polynilpotent series and related subgroups of a free group in much the same way as the conventional theory applies to the lower central series. The intention is to provide a theory of general application, however in §§ 17 and 19 new group-theoretic theorems are proved which involve the entire theory and illustrate its uses.
