Root Explanation

Supposedly is formed from "suppose" (from Old French *supposer*, meaning to place under or assume) and "-ly" (a suffix used to form adverbs). The word means in a manner that is assumed or believed to be true.

Memory Tip

Think of 'suppose' as placing an idea under consideration, and the '-ly' indicates how something is done. So, supposedly means something is believed to be true in a certain way.
