If you've mistakenly spelled "mpnday" instead of "Monday", here are a few correct alternatives to consider: 1) Monday, the correct spelling; 2) Mnday, by omitting the missing 'p'; 3) Moday, by replacing the incorrect 'p' with 'd'; 4) Mondy, by eliminating the unnecessary 'a.' Remember to double-check your spelling before finalizing any written work!
