Boxer with degree? Some might believe it (5)
I believe the answer is:
dogma
'some might believe it' is the definition.
I can't judge whether this definition defines the answer.
'boxer with degree?' is the wordplay.
'boxer' becomes 'dog' (I've seen this in other clues).
'with' means one lot of letters go next to another.
'degree?' becomes 'ma' (Master of Arts is a type of degree).
'dog'+'ma'='DOGMA'
Can you help me to learn more?
(Other definitions for dogma that I've seen before include "Inflexible principles" , "Inflexible principle" , "Blind faith required" , "Belief, precept" , "Authoritative doctrine" .)
