Was sick girl coming back? (5)
I believe the answer is:
ailed
'was sick' is the definition.
(I've seen this before)
'girl coming back?' is the wordplay.
I cannot quite understand how this works, but
'girl' could be 'aile' and 'aile' is found in the answer.
A single letter 'd' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for ailed that I've seen before include "Became sick" , "Delia (anag.)" , "Troubled" , "was giving trouble" , "Was unwell" .)
