Zero transported by flier from Los Angeles further down the line (5,2)
I believe the answer is:
later on
'zero transported by flier' is the definition.
I can't tell whether this defines the answer.
'los angeles further down the line' is the wordplay.
'los angeles' becomes 'LA' (abbreviation).
'further down' becomes 'eron' (I am not sure about this - if you are sure you should believe this answer much more).
'the' becomes 't' (the is pronounced as a 't' sound in some dialects).
'line' is an insertion indicator.
'la'+'eron'='laeron'
'laeron' going around 't' is 'LATER ON'.
'from' is the link.
Can you help me to learn more?
(Other definitions for later on that I've seen before include "'Subsequently, afterward (5,2)'" , "In the fullness of time" , "this evening?" , "in the future" , "Afterwards" .)
