Wild, turn over American play first (11)
I believe the answer is:
tempestuous
'wild' is the definition.
(I know that wild can be written as tempestuous)
'turn over american play first' is the wordplay.
I cannot quite see how this works, but
'turn' could be 'u' (a 'U-turn' is a kind of turn) and 'u' is found in the answer.
'over' could be 'o' (cricket abbreviation) and 'o' is located in the answer.
'american' could be 'us' (abbreviation for United States) and 'us' is located in the answer.
'play' could be 'tempest' (I've seen this before) and 'tempest' is present in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for tempestuous that I've seen before include "Seems put out (anag)" , "Very stormy" .)
