Have you noticed how our projects seem to cumulate by the end of the semester?

Absolutely! It feels like everything just piles up all at once.

Root Explanation
Cumulate → It is formed from "cum" (meaning together) and "ulare" (from the Latin root "ulatus", meaning to heap or pile up). The word "cumulate" means to gather or pile up things together.
Memory Tip
Think of gathering things 'together' ('cum') to create a 'heap' or 'pile' — that's what cumulate means.
