Irish in a ship or A380 (8)
I believe the answer is:
airliner
'a380' is the definition.
I can't tell whether this defines the answer.
'irish in a ship' is the wordplay.
'irish' becomes 'IR' (abbreviation).
'in' means one lot of letters goes inside another.
'ship' becomes 'liner' (as in an ocean liner).
'a'+'liner'='aliner'
'ir' put inside 'aliner' is 'AIRLINER'.
'or' is the link.
Can you help me to learn more?
(Other definitions for airliner that I've seen before include "Commercial plane" , "Passenger craft" , "One going aloft" , "Large aircraft" , "Large plane" .)
