I'm a little stuck... Click here to teach me more about this clue!

'dropping preliminaries sleep with newly-wed' is the definition.
I can't tell whether this defines the answer.

'storage space' is the wordplay.
'storage' becomes 'lumber' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'space' becomes 'room' (room is a kind of space).
'lumber'+'room'='LUMBER-ROOM'

'in' acts as a link.

Can you help me to learn more?

(Another definition for lumber room that I've seen is " store".)

I've seen this clue in The Guardian.
