Unbecoming pressure on N America to sever relations (5)
I believe the answer is:
inapt
'unbecoming' is the definition.
(thesaurus)
'pressure on n america to sever relations' is the wordplay.
I cannot really see how this works, but
'pressure' could be 'p' (abbreviation) and 'p' is found in the answer.
'on' could be 'at' (I've seen this in other clues) and 'at' is found within the remaining letters.
'n' is found in the answer.
A single letter 'i' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for inapt that I've seen before include "unqualified" , "Ill-suited" , "Unsuited" , "badly judged" , "Not fit, unsuitable" .)
