Supremo finds love in British ship (4)
I believe the answer is:
boss
'supremo' is the definition.
Both the answer and definition are singular nouns.
Maybe they are linked in a way I don't understand?
'love in british ship' is the wordplay.
'love' becomes 'o' (love means zero in tennis).
'in' means one lot of letters goes inside another.
'british' becomes 'b' (abbreviation e.g. in 'BBC').
'ship' becomes 'SS' (prefix in ship names eg SS Great Britain).
'b'+'ss'='bss'
'o' placed inside 'bss' is 'BOSS'.
'finds' acts as a link.
Can you help me to learn more?
(Other definitions for boss that I've seen before include "Master - stud" , "Head honcho" , "Informal employer or superior" , "Governor" , "(One's) chief" .)
