Of the citizens, 104, I see (5)
I believe the answer is:
civic
'of the citizens 104 i see' is the definition.
I can't tell whether this definition defines the answer.
'104 i see' is the wordplay.
'104' becomes 'CIV' (roman numerals).
'see' becomes 'C' (the word for the letter, according to Chambers).
'civ'+'i'+'c'='CIVIC'
Can you help me to learn more?
(Other definitions for civic that I've seen before include "This centre of town" , "Like, eg, town councils" , "Relating to citizens" , "Numbers of Romans" , "Relating to a city/town" .)
