Tax patience through victory around this planet (4,4)
I believe the answer is:
wear thin
'tax patience through' is the definition.
I can't tell whether this definition defines the answer.
'victory around this planet' is the wordplay.
'victory' becomes 'win' (a win is a victory).
'around' indicates putting letters inside.
'this planet' becomes 'earth' (Earth is an example).
'win' placed around 'earth' is 'WEAR THIN'.
Can you help me to learn more?
(Other definitions for wear thin that I've seen before include "Lose effect from overuse" , "Cease to convince" , "Get less convincing" , "start to be ineffective" , "Diminish - become less tolerable" .)
