Love-in-a-mist, recently watered (5)
I believe the answer is:
moist
'recently watered' is the definition.
The answer and definition are not the same part of speech. However, past participle verbs and adjectives occasionally mean the same thing.
'love-in-a-mist' is the wordplay.
'love' becomes 'o' (In tennis, 'love' means 'zero').
'in' means one lot of letters goes inside another.
'o' inserted inside 'mist' is 'MOIST'.
Can you help me to learn more?
(Other definitions for moist that I've seen before include "Dampish" , "sloppy" , "lubricated" , "Affected by tears, perhaps" , "Damp or clammy" .)
