[[An argument alignment pattern is the pattern of argument coding coexpression of two types of verb valency.]]
alignment system (STR) = a system defined by the co-expression of arguments of predicates in intransitive, transitive, and ditransitive constructions. Example: English expresses the one argument of an intransitive verb construction (The cats slept) in the same way as the semantically agentive argument of a transitive verb (The cats clawed the sofa): both arguments are expressed preceding the verb.
