Often rue funny figure (8)
I believe the answer is:
fourteen
'figure' is the definition.
The definition and answer can be both quantities as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'often rue funny' is the wordplay.
'funny' indicates an anagram.
'often'+'rue'='oftenrue'
'oftenrue' is an anagram of 'FOURTEEN'.
Can you help me to learn more?
(Other definitions for fourteen that I've seen before include "Pounds in a stone?" , "XIV" , "Number of lines in a sonnet" , "Fen route (anag)" .)
