Bit of beer I eradicated for stranger (6)
I believe the answer is:
eerier
'stranger' is the definition.
(eerie means odd or strange)
'bit of beer i eradicated' is the wordplay.
'bit of' indicates a hidden word.
'EERIER' is hidden in the letters of 'beer i eradicated'.
'for' acts as a link.
(Other definitions for eerier that I've seen before include "More strangely frightening" , "Spookier" , "Weirder" , "More mysterious" , "More spooky" .)
