Ways to tell them apart:
Phenomena is the plural form, which means more than one, while phenomenon is singular, meaning just one.
Think of phenomena like bacteria and phenomenon like bacterium. Singular words often end with -on, while plurals often end with -a.
When discussing multiple occurrences or examples, phenomena is the correct choice, as opposed to phenomenon when focusing on a singular event.
The letter a at the end of phenomena stands for all, suggesting more than one.
Use phenomenon if it is only one instance or event.
