Solvent, take note, capitalist is bearing up! (7)
I believe the answer is:
acetone
'solvent' is the definition.
(acetone is a kind of solvent)
'take note capitalist is bearing up' is the wordplay.
'is bearing' indicates the answer is hidden within the clue (the clue carries or bears the answer inside it).
'up' shows that the letters should be reversed in order (in down clue: letters go upwards).
'enoteca' is hidden within 'take note capitalist'.
'enoteca' written backwards gives 'ACETONE'.
(Other definitions for acetone that I've seen before include "Colourless solvent" , "Remover of nail polish" , "Eat once (anag) - solvent" , "it dissolves" , "chemical is the solution" .)
