Now, solve this: I'm trying to describe a situation in which a person prepares for an event, then realises the event won't happen, and so they undo their preparations, returning to a state of unpreparedness. Whenever I search for the opposite of 'prepare', I get words that describe a failure to prepare in the first place, or at best words that describe what happens to the preparations, not words that describe what happens to the person. Is there a word that captures what happens to the person as they return to a state of unpreparedness?.
Solution:
There is the phrase 'stand down' about which Lexico says stand down PHRASAL VERB 2 Relax or cause to relax after a state of readiness. If something doesn't happen soon, I reckon they'll stand us down. An ambulance crew was dispatched immediately, however they were stood down shortly after.
