YOU SAID:
Help i accidentally ate a fish
INTO JAPANESE
私が誤って魚を食べたのを助ける
BACK INTO ENGLISH
I help myself accidentally ate fish
INTO JAPANESE
私は誤って魚を食べた
BACK INTO ENGLISH
I mistakenly ate fish
INTO JAPANESE
私は誤って魚を食べた
BACK INTO ENGLISH
I mistakenly ate fish
That didn't even make that much sense in English.
