Two words 6 letters C-A-SE and 7 letters -R-I-ED first word most likely to be 'coarse' and I can't see any thing wrong with the rest of it. The I is from Eroica (Beethoven's 3rd symphony) the e from vole (small rodent - fits in with other words cutting across it) and the d I'm sure is right too.
So, COARSE -R-I-ED. Clue is "Gross" and I can only think "grained" but I'm not convinced.
