First uncountable ordinal

A first uncountable ordinal is a way of talking about something that has no start or end. It means that if you are talking about something that has a lot of parts, you can call them all the first uncountable ordinal. For example, if you were talking about all the buildings on a street, you could call them all the first uncountable ordinal. This makes it easier to talk about them without having to count each one.
