Disregards the love in the heart of a distraught singer (7)
I believe the answer is:
ignores
'disregards' is the definition.
('ignore' can be a synonym of 'disregard')
'love in the heart of a distraught singer' is the wordplay.
I cannot quite see how this works, but
'love' could be 'o' (love means zero in tennis) and 'o' is present in the answer.
an anagram of 'singer' is 'ignres' which is located in the remaining letters.
No letters remain.
This explanation may well be incorrect...
'the' acts as a link.
Can you help me to learn more?
(Other definitions for ignores that I've seen before include "Gives the cold shoulder" , "Runs away from" , "Snubs" , "Shrugs off" , "Passes over" .)
