I can understand that... I frequently make the mistake of typing 'and' when I meant 'an'.
Sometimes I think autocorrect adds the "d".
*blink* And the worst (or best, depending on viewpoint) I run into is the frequent use of "rouge" instead of the less-ruddy "rogue": rouge elephant; rouge annotation scales; dapper looking rouge; a rouge doing a little second-story work.
I'll leave this here...
how did the americanization of "couldn't care less" happen?
