Tackle difficulty without initially dithering (7)
I believe the answer is:
harness
'tackle' is the definition.
(I know that tackle can be written as harness)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for harness that I've seen before include "Parachute straps" , "Equine gear" , "Exploit, utilise" , "Control and use (resources)" , "riding equipment" .)
