Swedes, for example, introducing credit to poor vagrant (4,4)
I believe the answer is:
'swedes for example' is the definition.
I can't tell whether this defines the answer.
'introducing credit to poor vagrant' is the wordplay.
'introducing' means one lot of letters goes inside another (some letters introduced or inserted into others).
'credit' becomes 'cr' (abbreviation).
'vagrant' indicates an anagram (I've seen this in other clues).
'topoor' anagrammed gives 'rootop'.
'cr' going within 'rootop' is 'ROOT-CROP'.
Can you help me to learn more?
(Other definitions for root crop that I've seen before include "Maybe Murphy" , "Potatoes or carrots" , "Eg, potatoes" , "Swedes, say" , "Vegetable" .)
