What about "A big goldfish came early?"

[Kiyomice]

Thats fine. If it's not accepted, report it so it can be added.

How does one distinguish "large" from "big" in Korean?

[hippietrail]

They're synonyms. It's possible there's only one Korean word that covers both. Even if there are two or three Korean words that doesn't mean there will necessarily be a 1:1 mapping between them in the two languages.

Meaning, if you tried "large" and it said it was wrong, it's not wrong but you have to report it so they can add it.
