Now revealed to have come out and been followed (8)
I believe the answer is:
shadowed
'followed' is the definition.
(shadowing is a kind of following)
'now revealed to have come out and been' is the wordplay.
I cannot really understand how this works, but
'now' could be 'ad' (AD, Anno Domini, as opposed to BC, Before Christ) and 'ad' is present in the answer.
'revealed' could be 'showed' ('show' can be a synonym of 'reveal') and 'showed' is found in the remaining letters.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for shadowed that I've seen before include "Was stalker" , "Made gloomy" , "Followed secretly" .)
