Corn
generally means "the most common staple crop in the area". In Scotland, corn is rye. In England it's wheat. In furrin places it's maize. Not really relevant, I know, but I think it's quite interesting.

zea mays
is the proper name.

I've never heard it referred to as anything other than that, or any other grain referred to as corn.

Although similarly, in Brazil any kind of steak is often referred to as a 'beef', so you will find your meal could be a 'beef of chicken'.

'Corn' originally referred to pretty much any cereal seed and is still used in that sense sometimes. e.g. one might still talk about a barley corn, when reffering to a single grain. I think that is why there is some regional variation in what species it has become attached to.

Fair enough.
New one on me.
