Does it grow infernally? (4)
I believe the answer is:
fern
'does it grow' is the definition.
I can't tell whether this defines the answer.
'infernally?' is the wordplay.
'FERN' is hidden in amongst the letters.
However, I am unsure how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for fern that I've seen before include "Girl - bracken" , "Feathery frond plant" , "Bracken, for example" , "Feathery-leaved plant" , "Often shady plant" .)
