the proposition or event denoted by an apodosis clause. Example: in If you press this button, the door will open, the door will open is the apodosis; If you press this button is the protasis. Since the conditional relations are defined in terms of both logical implication and causal relation, the semantic use of 'apodosis' can be distinguished as 'apodosis proposition' or 'apodosis event'.
