Soon a geranium starts to wilt (3)
I believe the answer is:
sag
'wilt' is the definition.
(I've seen this in another clue)
'soon a geranium starts' is the wordplay.
'soon' becomes 's' (this might be a standard abbreviation of which I'm unaware).
'starts' says to take the initial letters.
The initial letter of 'geranium' is 'g'.
's'+'a'+'g'='SAG'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for sag that I've seen before include "Subsidence" , "Drop" , "Droop in the middle - it's gas" , "Hang down loosely" , "Slump" .)
