Detain in the right order, say (6)
I believe the answer is:
intern
'detain' is the definition.
(I know that intern is a more specific form of the action detain)
'in the right order say' is the wordplay.
'the' becomes 't' (the is pronounced as a 't' sound in some dialects).
'right order say' becomes 'ern' (I can't justify this - if you can you should believe this answer much more).
'in'+'t'+'ern'='INTERN'
Can you help me to learn more?
(Other definitions for intern that I've seen before include "Novice gaining experience" , "22 [IMPRISON]" , "cage" , "Confine as a prisoner" , "Hospital worker" .)
