Like plants, they are worth having (6)
I believe the answer is:
assets
'they are worth having' is the definition.
The definition suggests an adverb but the answer is not.
'like plants' is the wordplay.
'like' becomes 'as'.
'plants' becomes 'sets'.
'as'+'sets'='ASSETS'
Can you help me to learn more?
(Other definitions for assets that I've seen before include "valued possessions" , "Resources or holdings ( 6)" , "Advantages" , "Valuable property" , "Company's property" .)
