Good person with awful smell not fussed (6)
I believe the answer is:
stolid
'fussed' is the definition.
The answer and definition are not the same part of speech. However, past participle verbs and adjectives sometimes define each other.
'good person with awful smell' is the wordplay.
'good person' becomes 'st' (saint).
'with' says to put letters next to each other.
'awful smell' becomes 'olid' (I can't explain this - if you can you should give a lot more credence to this answer).
'st'+'olid'='STOLID'
'not' acts as a link.
Can you help me to learn more?
(Other definitions for stolid that I've seen before include "displaying little emotion" , "Not easily aroused" , "Calm, unanimated" , "Calm, dependable, unemotional" , "without much emotion" .)
