Upset a Rhode Island girl carrying goods (8)
I believe the answer is:
aggrieve
'upset' is the definition.
(I've seen this before)
'a rhode island girl carrying goods' is the wordplay.
'rhode island' becomes 'RI' (US postal abbreviation).
'girl' becomes 'eve' ().
'carrying' says to put letters next to each other (in a down clue, the bottom letters carry others).
'goods' becomes 'gg' (an abbreviation for 'good' repeated).
'ri'+'eve'='rieve'
'rieve' put after 'gg' is 'ggrieve'.
'a'+'ggrieve'='AGGRIEVE'
(Other definitions for aggrieve that I've seen before include "Ill-use" , "Make resentful" , "Cause to feel sorrow" , "Trouble" , "upset" .)
