It is necessary to distinguish between 'immediate' and 'non-immediate' tactical environments, and between 'identical' and 'different' tactical environments. The distinctions overlap. [...] In the sentences 'They left me' and 'They left late', the non-immediate tactical environments of 'me' and 'late' are identical (both occur in subject-predicate constructions), but their immediate tactical environments are different: 'me' occurs in a verb-goal construction, 'late' occurs in a construction of verb plus temporal attributive. For any one occurrence of a morpheme there is usually only one immediate tactical environment, but the number of its non-immediate tactical environments is limited only by the number of sets within sets of immediate constituents in which that morpheme is included. Hence immediateness of tactical environment is determined by the analysis into immediate constituents.
