A carefully composed, subtle, and surprising ambiguity-driven cartoon by Mick Stevens in the New Yorker 1/1&8/2024 issue (on-line on 12/2/23):
Were we expecting a baby?, conveying not ‘Were we pregnant?” but the surprising ‘Were we expecting a baby (to appear at the door, to visit us, to be delivered to us, etc.)?’ — compare Were we expecting a special-delivery letter? Were we expecting the Spanish Inquisition? (meanwhile, there’s a Page about MS cartoons on this blog)
From NOAD:
verb expect: … [c] believe that (someone or something) will arrive soon: Celia was expecting a visit.
verb phrase idiom be expecting (also be expecting a baby): informal be pregnant: his wife was expecting again.
