Kindly German entering African country (6)
I believe the answer is:
benign
'kindly' is the definition.
(thesaurus)
'german entering african country' is the wordplay.
'german' becomes 'g' (abbreviation).
'entering' indicates putting letters inside.
'african country' becomes 'benin' (Benin is an example).
'g' inserted inside 'benin' is 'BENIGN'.
(Other definitions for benign that I've seen before include "Medically curable" , "Genial, kindly" , "Favourable" , "Kindly or non-malignant" , "Harmless or kind" .)
