Company providing flights for one royal involved in a row (7)
I believe the answer is:
airline
'company providing flights' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'one royal involved in a row' is the wordplay.
'one' becomes 'i' (Roman numeral).
'royal' becomes 'r' (abbreviation).
'involved in' means one lot of letters goes inside another.
'row' becomes 'line' (as in a row of things).
'i'+'r'='ir'
'a'+'line'='aline'
'ir' put within 'aline' is 'AIRLINE'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for airline that I've seen before include "Qantas, for example" , "Business taking off" , "EasyJet, for example" , "Aircraft operating company" , "BA, say" .)
