Continue to take as passengers aboard (5,2)
I believe the answer is:
carry on
'passengers aboard' is the definition.
I can't judge whether this defines the answer.
'continue to take' is the wordplay.
'continue' becomes 'on' (I've seen this in other clues).
'to' means one lot of letters go next to another (I've seen this in other clues).
'take' becomes 'carry' (synonyms).
'on' after 'carry' is 'CARRY-ON'.
'as' acts as a link.
Can you help me to learn more?
(Other definitions for carry on that I've seen before include "kind of case one handles personally" , "Flirt" , "Display of fussing" , "Have an affair - cause a fuss - continue" , "Continue - to-do" .)
