1387: Ground vs Grinded Sep 28, 2018

In a dictionary, it will list the forms of 'grind' including the participle 'ground' and "(rare) grinded". Some spell-checking programs will even count 'grinded' as a misspelling, but this is becoming less accurate. 'Ground is still used dominantly for most grammatical objects, but in newer usages of the word the preferred participle is 'grinded'. This tends to crop up when the subject matter is about dancing, sex, or relating to marijuana, for which any form of 'grind' is fairly new. This could be because people don't care about traditional grammar, or because they are consciously trying to distinguish the two.
