Key Differences

Maize refers to the tall annual cereal grass that is widely cultivated for its yellow or white grains. It is scientifically known as Zea mays. Corn, on the other hand, is commonly used in American English to refer to the same crop, but the word can have a more flexible meaning in other English-speaking regions.
In the United States, maize and corn are terms that can be used interchangeably, as they often refer to the same plant and its grain. However, in countries like the UK, "corn" can refer to the primary cereal grain grown in the region, which might be wheat or barley.
The term maize is specific to the plant species Zea mays and is understood to mean the same thing globally. This scientific specificity makes "maize" the preferred term in academic and scientific contexts. Corn, meanwhile, can be subject to regional interpretations and is less precise when used in a global context.
To summarize, while both maize and corn can refer to the same cereal grain, the terminology can differ depending on the geographical and academic context. Maize has a more universally understood definition, whereas the meaning of corn can vary.
