@johnabs I think that distinction is meaningless here. That's like "oh cow technically can mean any female of a large animal, like the hippo, rhino, whale, or elephant". The scientific name of corn is Zea mays, so maize isn't really more specific or technical than corn.

@daeyoung Right, but Zea MAYS...maize...they're homophones. So maize is more specific than just corn 😋
