One stuck in a rut — a monk perhaps? (8,2,5)
I believe the answer is:
creature of habit
'a monk perhaps?' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.
'one stuck in a rut' is the wordplay.
I cannot really understand how this works, but
'one' could be 'i' (Roman numeral) and 'i' is located in the answer.
'a' is within the answer.
an anagram of 'rut' is 'tur' which is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Another definition for creature of habit that I've seen is " one who's predictable?".)
