Foolishly had scrap with Republican who won't deal fairly (4,5)
I believe the answer is:
card sharp
'won't deal fairly' is the definition.
I don't know anything about this answer so I can't tell whether this works.
'foolishly had scrap with republican' is the wordplay.
'foolishly' is an anagram indicator.
'with' means one lot of letters goes inside another.
'republican' becomes 'r' (abbreviation).
'had'+'scrap'='hadscrap'
'hadscrap' with letters rearranged gives 'cadsharp'.
'cadsharp' going around 'r' is 'CARD-SHARP'.
'who' is the link.
Can you help me to learn more?
(Other definitions for card sharp that I've seen before include "one manipulating clubs?" , "manipulating the pack?" , "Cheat at poker, say" , "wicked whist whizz?" , "Trickster" .)
