Event Type

Event type has two meanings depending on the tool: either the unique name of the event, or the class an event belongs to, such as pageview or click.

In Amplitude, event type is exactly what other tools call the event name, and its value is a string such as add_to_cart. In web analytics tools and in browser documentation the same phrase means the class an event belongs to: automatic, custom, system, or at the DOM level a type such as click or scroll. Before reading any report, establish which of the two the event type column holds, or counts get aggregated at the wrong level and the number of distinct events gets confused with the number of classes.
