Paying attention to ambassador, English, at the sound of a bell (7)
I believe the answer is:
heeding
'paying attention to' is the definition.
(I've seen this before)
'ambassador english at the sound of a bell' is the wordplay.
'ambassador' becomes 'HE' (His or Her Excellency).
'english' becomes 'E' (abbreviation).
'at' means one lot of letters go next to another.
'the sound of a bell' becomes 'ding' (I am not sure about this - if you are sure you should believe this answer much more).
'he'+'e'+'ding'='HEEDING'
Can you help me to learn more?
(Other definitions for heeding that I've seen before include "Paying attention to, taking note" , "Paying close attention to" , "Taking notice" , "Listening" , "Noting" .)
