'madrid gent' is the definition.
The definition suggests a singular noun which matches the answer.

'covered up an attempt to steal litres' is the wordplay.
'covered up' becomes 'hid' (I've seen this in another clue).
'an attempt' becomes 'ago' (I've seen this in other clues).
'to steal' means one lot of letters goes inside another.
'litres' becomes 'L' (abbreviation).
'ago' enclosing 'l' is 'algo'.
'hid'+'algo'='HIDALGO'

Can you help me to learn more?

(Other definitions for hidalgo that I've seen before include "Grandee" , "Spanish aristocrat" , "foreign gentleman" , "Spanish gentleman" , "Pachuca is capital of this Mexican state" .)
