YOU SAID:
Go to A jungle by yourself
INTO JAPANESE
自分でジャングルに行く
BACK INTO ENGLISH
I go to the jungle myself
INTO JAPANESE
私は自分でジャングルに行きます
BACK INTO ENGLISH
I go to the jungle by myself
INTO JAPANESE
私は自分でジャングルに行きます
BACK INTO ENGLISH
I go to the jungle by myself
That didn't even make that much sense in English.
