Indication from Englishman, to some extent (4)
I believe the answer is:
omen
'indication' is the definition.
(thesaurus)
'from englishman to some extent' is the wordplay.
'to some extent' says the answer is hidden in the clue.
'OMEN' is hidden within 'from englishman'.
(Other definitions for omen that I've seen before include "Portent, prophetic sign" , "Gloomy sign" , "Sign of things to come" , "Forewarning, harbinger" , "Harbinger, prophetic sign" .)
