Article covering vigil will stir them (6)
I believe the answer is:
awaken
'stir them' is the definition.
I can't judge whether this defines the answer.
'article covering vigil' is the wordplay.
'article' becomes 'an' (English indefinite article).
'covering' means one lot of letters goes inside another.
'vigil' becomes 'wake' (wake is a kind of vigil).
'an' enclosing 'wake' is 'AWAKEN'.
'will' is the link.
Can you help me to learn more?
(Other definitions for awaken that I've seen before include "Cause to remember" , "Come alive" , "Rouse (a feeling)" , "Call forth" , "Rouse from sleep" .)
