Be quiet and massage with a twiggy thing (5)
I believe the answer is:
shrub
'a twiggy thing' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'be quiet and massage' is the wordplay.
'be quiet' becomes 'sh' (both are said to tell someone to stop speaking).
'and' means one lot of letters go next to another.
'massage' becomes 'rub' (rub can mean to massage).
'sh'+'rub'='SHRUB'
'with' acts as a link.
Can you help me to learn more?
(Other definitions for shrub that I've seen before include "Mixed drink of rum, sugar, fruit-juice and spice" , "Small woody tree" , "Rose, perhaps" , "Plant - brush (anag)" , "Cordial" .)
