Gosh — person getting upset over a Spanish city! (7)
I believe the answer is:
cordoba
'spanish city' is the definition.
(I've seen this before)
'gosh person getting upset over a' is the wordplay.
'gosh' becomes 'cor' (I've seen this in other clues).
'person' becomes 'bod' (bod can informally mean a person or body).
'getting upset' says the letters should be written in reverse.
'over' says to put letters next to each other (in a down clue, some letters go over others).
'bod' in reverse letter order is 'dob'.
'cor'+'dob'+'a'='CORDOBA'
(Other definitions for cordoba that I've seen before include "ready for Nicaragua?" , "City in southern Spain and Spanish explorer" , "Moorish city" , "money for the Contras" , "Spanish destination" .)
