Strength can bring a certain amount of prowess (5)
I believe the answer is:
power
'strength' is the definition.
(I know that power is a type of strength)
'bring a certain amount of prowess' is the wordplay.
I cannot really understand how this works, but
'amount' could be 'w' (W is an example) and 'w' is present in the answer.
'of' could be 'o' and 'o' is present in the answer.
'a' could be 'per' (eg 'one a day' means 'one per day') and 'per' is found in the remaining letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'can' is the link.
Can you help me to learn more?
(Other definitions for power that I've seen before include "Supply with energy" , "Force - potentiality" , "Strength or authority" , "Ability to act or physical might" , "index" .)
