Reflecting well on one, though cold and tired out (6)
I believe the answer is:
credit
'reflecting well on one' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'cold and tired out' is the wordplay.
'cold' becomes 'C' (eg on taps).
'and' says to put letters next to each other.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'tired' anagrammed gives 'redit'.
'c'+'redit'='CREDIT'
'though' is the link.
Can you help me to learn more?
(Other definitions for credit that I've seen before include "acknowledgement of liability" , "In this, you have money in the bank" , "Note acknowledging a source of information" , "Honour or reliability - believe" , "Positive balance in account" .)
