Nasty present for tempter in garden (7)
I believe the answer is:
serpent
'tempter in garden' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'nasty present' is the wordplay.
'nasty' indicates an anagram (a nasty or wrong spelling).
'present' with letters rearranged gives 'SERPENT'.
'for' is the link.
Can you help me to learn more?
