Harry worried about old negative being unofficial (8)
I believe the answer is:
honorary
'unofficial' is the definition.
Both the definition and answer are adjectives. Perhaps there's an association between them I don't understand?
'harry worried about old negative' is the wordplay.
'worried' is an anagram indicator (worry can mean to interfere with or disturb).
'about' indicates putting letters inside.
'old' becomes 'o' (common abbreviation eg in OE for Old English).
'negative' becomes 'no' (no is a kind of negative).
'harry' is an anagram of 'hrary'.
'o'+'no'='ono'
'hrary' going around 'ono' is 'HONORARY'.
'being' acts as a link.
Can you help me to learn more?
(Other definitions for honorary that I've seen before include "Unpaid position or unearned degree" , "producing no income" , "(Of an office holder) unpaid" , "In name only" , "(Of title or office) not requiring one to perform services" .)
