At summer’s end, the garden can be even finer (7)
I believe the answer is:
grander
'even finer' is the definition.
I can't tell whether this definition defines the answer.
'at summer's end the garden can be' is the wordplay.
'at' means one lot of letters go next to another.
'end' says to take the final letters.
'can be' is an anagram indicator.
The last letter of 'summer' is 'r'.
'r' next to 'garden' is 'rgarden'.
'rgarden' is an anagram of 'GRANDER'.
Can you help me to learn more?
(Another definition for grander that I've seen is " more impressive".)
