Leaves hospital after cycle ride leads to accidental crash (7)
I believe the answer is:
spinach
'leaves' is the definition.
(I've seen this before)
'hospital after cycle ride leads to accidental crash' is the wordplay.
'hospital' becomes 'h'.
'after' means one lot of letters go next to another.
'cycle ride' becomes 'spin' (I've seen this before).
'leads to' suggests taking the first letters.
The first letters of 'accidental crash' is 'ac'.
'spin'+'ac'='spinac'
'h' put after 'spinac' is 'SPINACH'.
(Other definitions for spinach that I've seen before include "Some greens" , "Leaf vegetable" , "Popeye the Sailor's vegetable of choice" , "Popeye's vegetable" , "food" .)
