Deliver furniture, half-heartedly stopped by father (3,4)

Ross

I believe the answer is:

set free

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

'deliver' is the definition.
(I've seen this before)

'furniture half-heartedly stopped by father' is the wordplay.
I cannot really see how this works, but
'father' could be 'fr' (abbreviation as in a priest's title) and 'fr' is found within the answer.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for set free that I've seen before include "Deliver - release" , "no longer confined" , "Turn loose" , "Released" , "Liberate" .)
