Reluctant to draw? (8)
I believe the answer is:
backward
'reluctant' is the definition.
(similar in meaning)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for backward that I've seen before include "not at all apt" , "Retiring" , "Directed to the rear" , "Diffident, making poor progress" , "Retrograde" .)
