Parody of East German leaving Central American country somehow true (10)
I believe the answer is:
caricature
'parody' is the definition.
(I've seen this before)
'east german leaving central american country somehow true' is the wordplay.
'east german' becomes 'ost' ('east' in German).
'leaving' is a deletion indicator.
'central american country' becomes 'Costa Rica' (country in Central America).
'somehow' indicates anagramming the letters.
'costarica' with 'ost' taken out is 'carica'.
'true' with letters rearranged gives 'ture'.
'carica'+'ture'='CARICATURE'
'of' acts as a link.
(Other definitions for caricature that I've seen before include "Spitting Image" , "This is distorted" , "Comical representation" , "countenanced by Katisha" , "Parody" .)
