corollary

A corollary is an idea or event that naturally follows from another. It's like a smaller piece of the puzzle that fits into place after understanding the bigger picture.

When you hear someone mention a corollary, they usually mean that something else logically comes out of what was said before. For example, if a scientist explains that climate change is caused by rising CO2 levels in the atmosphere, a corollary might be that global temperatures will continue to rise unless we take action to reduce emissions. In this case, the corollary is an idea that naturally follows from the initial explanation. It's often used in academic or scientific writing, but can also come up in everyday conversations when people are discussing complex issues and want to explore their implications.
