Misplacing dosh, tall fair men experience financial difficulties (4,2,4,5)
I believe the answer is:
fall on hard times
'experience financial difficulties' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.
'misplacing dosh tall fair men' is the wordplay.
'misplacing' is an anagram indicator (I've seen 'misplaced' mean this).
'dosh'+'tall'+'fair'+'men'='doshtallfairmen'
'doshtallfairmen' is an anagram of 'FALL ON HARD TIMES'.
Can you help me to learn more?
(Another definition for fall on hard times that I've seen is " Get into debt perhaps".)
