Bashful, but will have a fling (3)
I believe the answer is:
shy
This clue might be a double definition.
'bashful' is the first definition.
(bashful means shy or reserved)
'a fling' is the second definition.
(shy can mean to throw)
'but will have' acts as a link.
This may not be correct. Some or all of it may belong to one of the definitions.
Can you help me to learn more?
(Other definitions for shy that I've seen before include "Reticent" , "Timid (around people)" , "Short of" , "Retiring; fling" , "Pitch" .)
