No good ingredient of soilless composts (3)
I believe the answer is:
ill
'no good' is the definition.
Both the definition and answer are adjectives. Maybe they are linked in a way I don't understand?
'ingredient of soilless composts' is the wordplay.
'ingredient of' indicates a hidden word.
'ILL' is hidden in the letters of 'soilless composts'.
Can you help me to learn more?
(Other definitions for ill that I've seen before include "Hardly - sick" , "Not in the pink" , "I will (abbrev.) (1'2)" , "Unwell, sick" , "Ailing" .)
