His ark is rebuilt to be stylish and speedy (6)
I believe the answer is:
rakish
'be stylish and speedy' is the definition.
I can't judge whether this defines the answer.
'his ark is rebuilt' is the wordplay.
'is rebuilt' indicates anagramming the letters.
'his'+'ark'='hisark'
'hisark' with letters rearranged gives 'RAKISH'.
'to' is the link.
Can you help me to learn more?
(Other definitions for rakish that I've seen before include "Given to philandering" , "Jaunty; fast-looking (boat)" , "Jaunty and irresponsible" , "Dashing, devil-may-care" , "Dashing and slightly disreputable" .)
