the semantic relation between two events where one event serves as the opposite of the intended outcome of bringing about the other event. In this respect, the apprehensional relation is a negative version of the purpose relation. Examples: I grabbed a stick lest he attack me is a figure--ground construal of the simultaneous relation in an adverbial clause construction, and Grab a stick or he will attack you is a complex figure construal of the relation in a coordinate clause construction. In the figure--ground construal, the negatively intended event is construed as the ground. As with the purpose relation, the apprehensional event is unrealized; the complex figure construal is possible because the matrix clause event is also unrealized. (Section 15.3.1)
