Break articles possessed by British Queen (8)
I believe the answer is:
breather
'break' is the definition.
(I've seen this before)
'articles possessed by british queen' is the wordplay.
'articles' becomes 'athe' (two examples of the part-of-speech: a+the).
'possessed by' indicates putting letters inside.
'british' becomes 'br'.
'queen' becomes 'er' (abbreviation for Elizabeth Regina).
'br'+'er'='brer'
'athe' put within 'brer' is 'BREATHER'.
(Other definitions for breather that I've seen before include "Short pause for rest" , "lung, possibly?" , "Rather be having a rest - inhale" , "Recovery time" , "An informal break - inhale and exhale" .)
