(all) over again
Again from the very beginning. I realized halfway through making the cake that the eggs had expired, so I had throw the batter away and start all over again. This is really not an acceptable standard of work—I'm afraid I need you to do it over again.
(all) over again
starting over completely again; going through something completely yet another time. Do I have to go through this all over again? Please start over again for those who came in late.
over again
Once more, as in The conductor had them start the symphony over again. [Mid-1500s]
(all) over aˈgain
once more; for a second time: I’m not sure if I could stand seeing that DVD all over again.He told me the work was so bad that I would have to do it over again.
