Sense: noun/1

For sense 1, 'phenomenon' is useful when something can be observed and seems special, surprising, or worth explaining. 'Event' is the broad everyday choice for something that happens, without suggesting mystery or scientific interest. 'Occurrence' is more formal and often sounds factual or written. 'Effect' shifts attention to the result that one thing produces in another, so it is narrower than 'phenomenon'. You can call the northern lights a natural phenomenon, but a school sports day is simply an event. A sudden color change in a lab test may be an effect, while the whole pattern behind it can be the phenomenon scientists want to explain.

Etymology

GreekLatinEnglish

English borrowed 'phenomenon' from Latin, which had taken it from Greek 'phainomenon', meaning 'something that appears' or 'comes into view'. That older idea of something appearing to the eye or mind still fits the modern word, which often refers to something people notice, observe, and try to explain.
