He wrote, using special nibs, about the Norwegian centre (5)
I believe the answer is:
ibsen
'he wrote' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'special nibs about the norwegian centre' is the wordplay.
'special' indicates anagramming the letters.
'about' means one lot of letters goes inside another.
'centre' means to look at the middle letters.
The central letter of 'norwegian' is 'e'.
'nibs' is an anagram of 'ibsn'.
'ibsn' enclosing 'e' is 'IBSEN'.
'using' acts as a link.
Can you help me to learn more?
(Other definitions for ibsen that I've seen before include "Norwegian dramatist, Henrik (1828-1906)" , ""Doll's House" dramatist" , "See 7 Down" , "foreign author" , "Norwegian dramatist of 'Hedda Gabler'" .)
