Get dressed in case there's no beer (6)
I believe the answer is:
enrobe
'get dressed' is the definition.
(I've seen this in another clue)
'case there's no beer' is the wordplay.
'no beer' can be anagrammed to 'ENROBE'.
However, I'm not sure how this is indicated.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for enrobe that I've seen before include "put on gown" , "Dress, put on vestments" , "put on formally ..." , "Don a vestment" , "Clad ceremonially" .)
