Theologian tucking into beers becomes muddled (6)
I believe the answer is:
addles
'becomes muddled' is the definition.
I can't judge whether this definition defines the answer.
'theologian tucking into beers' is the wordplay.
'theologian' becomes 'DD' (Doctor of Divinity degree).
'tucking into' indicates putting letters inside.
'beers' becomes 'ales' (ale is a type of beer).
'dd' put inside 'ales' is 'ADDLES'.
Can you help me to learn more?
(Other definitions for addles that I've seen before include "Confuses, befuddles" , "Muddles, confuses" , "Confuses or becomes rotten" , "Confuses like bad egg" , "Makes rotten - makes muddled" .)
