YOU SAID:
I saw a saw saw a saw like a sea saw sawing a sawn sea saw
INTO JAPANESE
私は鋸を見た、鋸は海の鋸のようだった、鋸は海の鋸を切っている
BACK INTO ENGLISH
I saw a saw, the saw was like a sea saw, the saw is cutting the sea saw
INTO JAPANESE
私はのこぎりを見た、そののこぎりは海ののこぎりのようだった、そののこぎりは海ののこぎりを切っている
BACK INTO ENGLISH
I saw a saw, the saw was like a sea saw, the saw is cutting the sea saw
That didn't even make that much sense in English.
