Strange admissions of debt by a low fellow (7)
I believe the answer is:
curious
'strange' is the definition.
(synonyms)
'admissions of debt by a low fellow' is the wordplay.
'admissions of debt' becomes 'IOUs' (I Owe You's).
'by' is a charade indicator (letters next to each other).
'a low fellow' becomes 'cur' (I can't justify this - if you can you should believe this answer much more).
'ious' put after 'cur' is 'CURIOUS'.
Can you help me to learn more?
(Other definitions for curious that I've seen before include "Unusual; eager to learn" , "Strange, unusual" , "Questioning" , "Odd - inquisitive" , "Intrigued" .)
