Those little delays dad exploits (6)
I believe the answer is:
pauses
'those little delays' is the definition.
I can't tell whether this definition defines the answer.
'dad exploits' is the wordplay.
'dad' becomes 'pa' ('pa' can be a synonym of 'dad').
'exploits' becomes 'uses' (use is a kind of exploit).
'pa'+'uses'='PAUSES'
Can you help me to learn more?
(Other definitions for pauses that I've seen before include "Temporary halts" , "Short breaks in business" , "Stops or rests briefly" , "Short silences" , "Temporary interruptions" .)
