Significant hint in Arbuthnot epistle (4)
I believe the answer is:
note
'significant hint' is the definition.
'note' can be an answer for 'hint' (thesaurus). I'm unsure of the 'significant' bit.
'in arbuthnot epistle' is the wordplay.
'in' indicates the answer is hidden within the clue.
'NOTE' is hidden within 'arbuthnot epistle'.
Can you help me to learn more?
(Other definitions for note that I've seen before include "Make a record of" , "Quaver, say" , "A piece of paper money" , "Short written message" , "mention" .)
