Out for the week-end, she could be lucky (4)
I believe the answer is:
lucy
'out for' is the definition.
The definition suggests a singular noun which matches the answer.
'week-end she could be lucky' is the wordplay.
I cannot really see how this works, but
'she' could be 'lu' and 'lu' is present in the answer.
This explanation may well be incorrect...
'the' acts as a link.
Can you help me to learn more?
(Other definitions for lucy that I've seen before include "-- Locket, nursery rhyme" , "- in the Sky with Diamonds (The Beatles)" , "Ms Locket?" .)
