Disregard Italian gent with no hat (6)
I believe the answer is:
ignore
'disregard' is the definition.
(synonyms)
'italian gent with no hat' is the wordplay.
'italian' becomes 'I' (abbreviation for Italian).
'gent' becomes 'gore' (I can't justify this - if you can you should believe this answer much more).
'with' means one lot of letters goes inside another.
'hat' suggests taking the first letters (I've seen 'hats' mean this (in a down clue, the letter at the top of the word)).
The first letter of 'no' is 'n'.
'gore' going around 'n' is 'gnore'.
'i'+'gnore'='IGNORE'
Can you help me to learn more?
(Other definitions for ignore that I've seen before include "Fail to consider" , "Intentionally disregard" , "Fail to observe" , "Slight" , "Region (anag)" .)
