Emphasise trouble (4,2)
I believe the answer is:
play up
This might be a double definition.
'emphasise' is the first definition.
(playing up is a kind of emphasizing)
'trouble' is the second definition.
Although both the answer and definition are verbs in their base form, I don't understand how they can define each other.
Can you help me to learn more?
(Other definitions for play up that I've seen before include "Be painful - misbehave" , "Cause problems" , "(Equipment) start malfunctioning" , "make too much of a story" , "Emphasise the importance" .)
