YOU SAID:
Jeff eats potatoes with cheese in them
INTO JAPANESE
ジェフはジャガイモにチーズを食べる
BACK INTO ENGLISH
Jeff eats cheese potatoes
INTO JAPANESE
それはチーズを食べません
BACK INTO ENGLISH
It doesn't eat cheese
INTO JAPANESE
それはチーズを食べません
BACK INTO ENGLISH
It doesn't eat cheese
That didn't even make that much sense in English.
