Root Explanation

Thereupon is formed from "there" (from Old English "þær", meaning at that place) and "upon" (from Old English "uppon", meaning on or upon). The word "thereupon" means at that place or immediately after that event.

Memory Tip

Think of 'there' as indicating a specific place and 'upon' as meaning on or after something — so 'thereupon' refers to something happening right after a specific event.
