To mix together; to blend or combine different things into one mixture.
From Latin commixere, from com- 'together' + miscere 'to mix'. The word is archaic or literary, largely replaced by modern terms like mix, blend, or combine.
Commix survives mainly in legal documents and old literature, but it's a beautiful word that emphasizes the thoroughness of mixing—com- means 'with/together' in a way that regular 'mix' doesn't quite capture.
