YOU SAID:
Nolan has an egg his egg is big
INTO JAPANESE
ノーランは彼の卵が大きい卵を持っています
BACK INTO ENGLISH
Nolan his egg has big eggs
INTO JAPANESE
彼の卵は大きな卵を持っています
BACK INTO ENGLISH
His egg has big eggs
INTO JAPANESE
彼の卵には大きな卵がある
BACK INTO ENGLISH
His egg has big eggs
That didn't even make that much sense in English.
