Gentleman upset about newspaper quarrels (5)
I believe the answer is:
rifts
'quarrels' is the definition.
Although both the answer and definition are plural nouns, I can't understand how one could define the other.
'gentleman upset about newspaper' is the wordplay.
'gentleman' becomes 'sir' (a man may be addressed as sir).
'upset' says the letters should be written backwards.
'about' means one lot of letters goes inside another.
'newspaper' becomes 'FT' (Financial Times newspaper).
'sir' written backwards gives 'ris'.
'ris' going around 'ft' is 'RIFTS'.
Can you help me to learn more?
(Other definitions for rifts that I've seen before include "Deep divides" , "Schisms" , "Breaks, severances" , "Clefts or fissures." , "differences ..." .)
