Such a face as the wrinkled Enid has at fifty-four? (5-2)
I believe the answer is:
lived-in
'such a face' is the definition.
I can't judge whether this definition defines the answer.
'the wrinkled enid has at fifty-four?' is the wordplay.
'the wrinkled' indicates anagramming the letters (I've seen this in other clues).
'has' means one lot of letters goes inside another.
'at' says to put letters next to each other.
'fifty' becomes 'l' (roman numeral).
'four?' becomes 'iv' (roman numeral).
'enid' with letters rearranged gives 'edin'.
'l' next to 'iv' is 'liv'.
'edin' going around 'liv' is 'LIVED-IN'.
'as' is the link.
Can you help me to learn more?
(Another definition for lived-in that I've seen is " (Of face) marked by experience".)
