The whole clue is the definition (& lit or double definition).
How the clue works
The whole clue is an &lit, meaning it works as both definition and wordplay at once. Take the first letter of each word — Always, Come, Rain, Or, Shine, Tongue, In, Cheek — and those initials spell out ACROSTIC, which is of course the very technique being used to conceal it.
