An elaboration on the transitivity system network introduced by M. A. K. Halliday is developed. This extension consists of a separate feature system network for the participant role of “beneficiary”. The formulation of the proposed grammar rules to conjoin this network and Halliday's is facilitated by building up the transitivity network to describe "systemically” and uniquely each type of benefactive and range clause presented by Halliday. Systemic descriptions of these clauses are given as examples throughout the discussion.
