Detain the latest flier (6)
I believe the answer is:
intern
'detain' is the definition.
(I've seen this before)
'the latest flier' is the wordplay.
'the latest' becomes 'int' (I can't explain this - if you can you should give a lot more credence to this answer).
'flier' becomes 'ern' (ern is a kind of birdanimal).
'int'+'ern'='INTERN'
Can you help me to learn more?
(Other definitions for intern that I've seen before include "Young American 18" , "Imprison (enemy aliens)" , "Confine as a prisoner" , "Work experience trainee" , "Official language of Pakistan" .)
