SOS Jean in Costa Rica’s capital (3,4)
I believe the answer is:
san jose
'costa rica's capital' is the definition.
(I've seen this in another clue)
'sos jean' is the wordplay.
'sos jean' can be anagrammed to 'SAN JOSE'.
However, I'm unsure how the anagram is indicated.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for san jose that I've seen before include "US city" , "Residence for Californians" , "American city" , "Costa-Rican capital" , "Do you know the Way to - -? (Dionne Warwick)" .)
