Things that did not need to happen, or were meant to and didn’t
The rule
English keeps apart two kinds of unnecessary past action. needn’t have + past participle means you did something that turned out to be unnecessary: You needn’t have brought food — there was plenty (you brought it). didn’t need to + infinitive usually means it was unnecessary, so it probably was not done: I didn’t need to show my ticket (and I didn’t). Plans that failed have their own forms: was / were supposed to (an expectation or arrangement that was not met: The parcel was supposed to arrive on Monday), was meant to (similar, often informal), was to have + past participle (formal: She was to have opened the exhibition), and was going to (an intention that changed). should have criticises, was supposed to simply states the gap between plan and reality.
needn’t have + past participle (done, but unnecessary) · didn’t need to + verb (unnecessary, probably not done) · was supposed / meant to + verb (plan not met) · was to have + past participle (formal) · was going to (intention that changed)
Examples
