YOU SAID:
There was once a ship that put to sea
INTO JAPANESE
かつて海に出た船がありました
BACK INTO ENGLISH
Once upon a time there was a ship that went out to sea
INTO JAPANESE
昔々、海に出た船がありました
BACK INTO ENGLISH
Once upon a time there was a ship that went out to sea
That didn't even make that much sense in English.
