Root Explanation

Therein is formed from "there" (from Old English "þær", meaning at that place) and "in" (from Old English "in", meaning within). The word "therein" means in that place or within that context.

Memory Tip

Think of 'there' as a specific place and 'in' as being inside it — that's how 'therein' means being inside that specific place.
