Doctor sent in light meal for Leo, for example (13)
I believe the answer is:
constellation
'leo for example' is the definition.
(leo is a kind of constellation)
'doctor sent in light meal' is the wordplay.
I cannot quite see how this works, but
an anagram of 'sent' is 'nste' which is present in the answer.
'meal' could be 'collation' (collation is a kind of meal) and 'collation' is found in the remaining letters.
This accounts for all the letters.
This may be the basis of clue (or it may be nonsense).
'for' acts as a link.
Can you help me to learn more?
(Other definitions for constellation that I've seen before include "Star group" , "Formation of stars" , "Cassiopeia, for example" , "Group of stars" , "E.g Orion, Andromeda" .)
