Dutch settler caging cross dog (5)
I believe the answer is:
boxer
'dog' is the definition.
(boxer is a kind of dog)
'dutch settler caging cross' is the wordplay.
'dutch settler' becomes 'boer' (I am not sure about the 'dutch' bit.).
'caging' means one lot of letters goes inside another (I've seen this in other clues).
'cross' becomes 'x' (X is cross-shaped).
'boer' placed around 'x' is 'BOXER'.
Can you help me to learn more?
(Other definitions for boxer that I've seen before include "Dog - fighter" , "Pug - dog" , "one that's accustomed to fighting" , "Breed of stocky short-haired dog" , "Person assisted by a second" .)
