Deduces (6)
I believe the answer is:
infers
'deduces' is the definition.
('infer' can be a synonym of 'deduce')
This is the entire clue.
(Other definitions for infers that I've seen before include "Deduces, concludes" , "Concludes from the facts" , "Takes or draws meaning from" , "Works out" , "'Derives, concludes (6)'" .)
