 A different perspective has emerged in recent years to explain the why certain triggers seem to only result in a presupposition part of the time. Rather than proposing that there is variation in triggering, some linguists interpret this behavior as the result of variation in the inherent cancellability among triggers. Abusch (2002, 2010) distinguishes between ‘soft’ triggers which are weak and context-dependent and ‘hard’ triggers, which are resistent to cancellation. For example, she classifies the achievement verb win, in (58a), as a soft trigger, since the presupposition that John participated in the race is contextually defeasible, whereas the cleft construction in (58b) is considered a hard trigger because it cannot be cancelled by the speaker by explicitly expressing ignorance.
