Playful spirit with a sad plant grown indoors (10)
I believe the answer is:
aspidistra
'plant grown indoors' is the definition.
I can't judge whether this defines the answer.
'playful spirit with a sad' is the wordplay.
'playful' indicates an anagram.
'with' says to put letters next to each other.
'a'+'sad'='asad'
'spirit' put after 'asad' is 'asadspirit'.
'asadspirit' anagrammed gives 'ASPIDISTRA'.
Can you help me to learn more?
(Other definitions for aspidistra that I've seen before include "leafy plant" , "Star is paid (anag) - plant" , "Houseplant of lily family" , "Large houseplant" , "Iris adapts (anag) - indoor plant" .)
