I get out with difficulty after salesman turns blue (10)
I believe the answer is:
periwinkle
'blue' is the definition.
(shade of blue)
'i get out with difficulty after salesman turns' is the wordplay.
I cannot quite see how this works, but
'i' is found in the answer.
'get' could be 'win' (winning is a kind of getting) and 'win' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for periwinkle that I've seen before include "This plant may be poisonous" , "Ornamental plant" , "Evergreen creeper" , "Plant; mollusc" , "Blue" .)
