YOU SAID:
I have lost the ability to person
INTO JAPANESE
私は人に対する能力を失いました
BACK INTO ENGLISH
I lost my ability for people
INTO JAPANESE
私は人々の能力を失いました
BACK INTO ENGLISH
I lost the ability of people
INTO JAPANESE
私は人々の能力を失いました
BACK INTO ENGLISH
I lost the ability of people
That didn't even make that much sense in English.
