Free time amid children's bricks (3,2)
I believe the answer is:
let go
'free' is the definition.
(I've seen this in another clue)
'time amid children's bricks' is the wordplay.
I cannot really see how this works, but
'time' could be 't' (abbreviation) and 't' is located in the answer.
'bricks' could be 'lego' (plastic brick toys) and 'lego' is located in the remaining letters.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for let go that I've seen before include "Dismiss (from ones thoughts?)" , "Don't hold on" , "Release or free" , "Set at liberty, loose grip on" , "Release - relax one's grasp" .)
