Its passengers will be late (6)
I believe the answer is:
hearse
This clue might be a double definition.
'its passengers' is the first definition.
I know that 'passengers' relates to this answer.
'be late' is the second definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'will' is the link.
Can you help me to learn more?
(Other definitions for hearse that I've seen before include "Vehicle for carrying the dead" , "final vehicle?" , "Vehicle for conveying a coffin" , "Carriage for a corpse" , "Undertaker's vehicle" .)
