Comfort thus with fancy material (6)
I believe the answer is:
solace
'comfort' is the definition.
(I know that comfort can be written as solace)
'thus with fancy material' is the wordplay.
'thus' becomes 'so' (synonyms).
'with' says to put letters next to each other.
'fancy material' becomes 'lace' (lace is a kind of material. I am not sure about the 'fancy' bit.).
'so'+'lace'='SOLACE'
Can you help me to learn more?
(Other definitions for solace that I've seen before include "Comfort in misery" , "Comfort in time of disappointment or sorrow" , "Comport" , "Comfort and reassurance" , "console" .)
