Group starts renting cruise liners through transport company (6)
I believe the answer is:
circle
'group' is the definition.
(I've seen this in other clues)
'starts renting cruise liners through transport company' is the wordplay.
'starts' indicates taking the first letters.
'through' indicates putting letters inside (inserted letters go through the word).
'transport company' becomes 'cie' (I am not sure about this - if you are sure you should believe this answer much more).
The first letters of 'renting cruise liners' is 'rcl'.
'rcl' put into 'cie' is 'CIRCLE'.
Can you help me to learn more?
(Other definitions for circle that I've seen before include "part of theatre" , "overlooked by the gods" , "Group; move round" , "Theatre's upper tier" , "Seats above theatre stalls" .)
