Article about old British plane safeguards (6)
I believe the answer is:
object
'article' is the definition.
(both can mean a thing or item)
'about old british plane safeguards' is the wordplay.
'about' is an insertion indicator.
'old' becomes 'o' (abbreviation).
'british' becomes 'b' (abbreviation e.g. in BBC).
'plane' becomes 'jet plane' (jet plane).
'safeguards' becomes 'c' (I can't explain this - if you can you should give a lot more credence to this answer).
'o'+'b'+'jet'='objet'
'objet' going around 'c' is 'OBJECT'.
Can you help me to learn more?
(Other definitions for object that I've seen before include "end" , "Tangible thing" , "Aim - to argue against - something" , "Idea" , "Take exception to the thing" .)
