Hide boat with start of cyclone forecast (7)
I believe the answer is:
coracle
'forecast' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'hide boat with start of cyclone' is the wordplay.
'hide' becomes 'coral' (I am not sure about this - if you are sure you should believe this answer much more).
'boat' becomes 'e'.
'with' means one lot of letters goes inside another.
'start of' indicates taking the first letters.
The first letter of 'cyclone' is 'c'.
'coral'+'e'='corale'
'corale' going around 'c' is 'CORACLE'.
Can you help me to learn more?
(Other definitions for coracle that I've seen before include "Small round boat of skin over a wicker frame" , "craft" , "Small primitive boat" , "Oval rowing boat" , "Welsh version of the currach" .)
