Wish a foreign student — one from East Africa (7)
I believe the answer is:
swahili
'east africa' is the definition.
Both the definition and answer are singular nouns.
Perhaps there's a link between them I don't understand?
'wish a foreign student one' is the wordplay.
'foreign' indicates an anagram (foreign order of the letters).
'student' becomes 'l' (as in L-plates for learner drivers).
'one' becomes 'I' (Roman numeral).
'wish'+'a'='wisha'
'wisha' with letters rearranged gives 'swahi'.
'swahi'+'l'+'i'='SWAHILI'
'from' is the link.
Can you help me to learn more?
(Other definitions for swahili that I've seen before include "heard in parts of Africa" , "Language giving us bwana, safari" , "Widely-spoken Bantu language" , "Common language in East Africa" , "African people" .)
