YOU SAID:
I heared it through the grapevine
INTO JAPANESE
私はブドウを介してそれを聞いた
BACK INTO ENGLISH
I heard it through the grapes
INTO JAPANESE
私はブドウを通してそれを聞いた
BACK INTO ENGLISH
I heard that through the grapes
INTO JAPANESE
私はブドウを通してそれを聞いた
BACK INTO ENGLISH
I heard that through the grapes
That didn't even make that much sense in English.
