'Cereal' or 'serial'?
Cereal is primarily used to refer to grains such as wheat or rye, or to breakfast food made from roasted grains, as in:
I had a bowl of cereal with milk for breakfast.
Whereas serial is most often used as an adjective meaning 'taking place in a series or sequence', or 'a person repeatedly following a behaviour pattern', for example, 'a serial publication' or 'a serial killer'.
Serial can also be used as a noun to mean 'a story told in regular instalments', for example in a magazine or on radio, television, or podcast, as in:
The crime serial was watched by people around the world.
