Stood up, suppressing cry of disgust with couple becoming more indecent (9)
I believe the answer is:
naughtier
'more indecent' is the definition.
Both the answer and definition are comparative adjectives. Perhaps there's a link between them I don't understand?
'stood up suppressing cry of disgust with couple' is the wordplay.
I cannot really understand how this works, but
'couple' could be 'tie' (I've seen this in another clue) and 'tie' is located in the answer.
'cry of disgust' could be 'ugh' (expression of disgust) and 'ugh' is located in the answer.
This explanation may well be incorrect...
'becoming' acts as a link.
Can you help me to learn more?
(Other definitions for naughtier that I've seen before include "More mischievous" , "more unruly" , "Less well behaved" , "Worse" , "More badly behaved" .)
