Turning 'trust me' into 'here's the receipt.'

means The act of backing up a claim with solid evidence or proof so it holds up to scrutiny.

from Traces back to the Latin substantia — 'substance,' the stuff something is actually made of — built from sub- ('under') plus stare ('to stand'). To substantiate something is, quite literally, to give it something to stand on: to turn a claim from thin air into a thing with real underpinning.
