English doctor, French king and the German add detail (9)
I believe the answer is:
embroider
'add detail' is the definition.
I can't judge whether this defines the answer.
'english doctor french king and the german' is the wordplay.
'english' becomes 'e' (abbreviation).
'doctor' becomes 'MB' (Bachelor of Medicine, Medicinae Baccalaureus).
'french king' becomes 'roi' ('king' in French).
'and' says to put letters next to each other.
'the german' becomes 'der' ('the' in German).
'e'+'mb'+'roi'+'der'='EMBROIDER'
Can you help me to learn more?
(Other definitions for embroider that I've seen before include "Exaggerate" , "Do decorative needlework" , "Ornament with needlework" , "Add (fictitious) detail to" , "stitch" .)
