Gathers fern is in a new order (6)
I believe the answer is:
infers
'gathers fern is in a new order' is the definition.
I can't tell whether this defines the answer.
'gathers fern is in' is the wordplay.
'gathers' indicates an anagram (I've seen 'gathered' mean this).
'in' is an insertion indicator.
'fern' with letters rearranged gives 'nfer'.
'nfer' inserted into 'is' is 'INFERS'.
Can you help me to learn more?
(Other definitions for infers that I've seen before include "Takes or draws meaning from" , "Concludes by reasoning" , "Works out" , "Deduces, concludes" , "'Derives, concludes (6)'" .)
