A friend of mine (who, as far as I know, doesn't have English as a first language, though is fluent) mentioned how odd it was that English had the word admix, and quoted a dictionary definition that stated that it was a synonym of mix. I supposed that an admix was a mix made just by adding two materials together, whereas a mix involved stirring.
This is the entry I found:
tr. & intr.v. ad·mixed, ad·mix·ing, ad·mix·es
To mix; blend.
Am I right that the word is redundant, or does it have another use?
