Over in Florida was this often dried up? (4)
I believe the answer is:
wadi
'this often dried up?' is the definition.
The definition suggests a singular noun which matches the answer.
'over in florida was' is the wordplay.
'over' shows that the letters should be reversed in order.
'in' indicates the answer is hidden within the clue.
'idaw' is hidden in the letters of 'florida was'.
'idaw' backwards is 'WADI'.
Can you help me to learn more?
(Other definitions for wadi that I've seen before include "Periodic water channel" , "Mostly dry river valley" , "Valley usually dry" , "Seasonal watercourse" , "Seasonally dry watercourse" .)
