What's good in garden, making end of lawn right? (5)
I believe the answer is:
edger
'end of lawn right?' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe there's an association between them I don't understand?
'what's good in garden' is the wordplay.
'what's good' becomes 'g' (abbreviation).
'in' means one lot of letters goes inside another.
'garden' becomes 'eder' (I am not sure about this - if you are sure you should believe this answer much more).
'g' inserted into 'eder' is 'EDGER'.
'making' is the link.
Can you help me to learn more?
(Other definitions for edger that I've seen before include "Trimming tool" , "Gardening tool" , "Someone moving slowly" .)
