Foreign accent I called cultivated (7)
I believe the answer is:
cedilla
'foreign accent' is the definition.
(I've seen this before)
'i called cultivated' is the wordplay.
'cultivated' indicates an anagram.
'i'+'called'='icalled'
'icalled' anagrammed gives 'CEDILLA'.
(Other definitions for cedilla that I've seen before include "foreign accent" , "Diacritical mark" , "Sign to soften C" , "Mark, in foreign language" , "Mark under a consonant in French, perhaps" .)
