Morphology

shadow + for + the + substance

The meaning ('mistaking appearance for reality') is largely derivable from the parts: 'shadow' (appearance), 'for' (in place of / instead of), and 'substance' (essence). However, the construction is non‑standard and stylistically odd in English (learners expect a verb like 'mistake X for Y' or a clearer phrasing), so a B1 learner who knows the words may still find the expression unfamiliar or slightly confusing.

Etymology

Shadow for the substance gives a clear image: a shadow looks like a thing but is not the real substance that made it. So it means 'to mistake appearance for reality' or to treat something false as if it were true.
