Unfurl → It is formed from "un-" (meaning not or opposite) and "furl" (from Old English "furlian", meaning to roll up or to wrap). The word "unfurl" means to unroll or open something that was previously rolled up or wrapped.
Think of 'un-' meaning not or opposite, and 'furl' meaning to roll up. So, when you unfurl something, you are opening it up from being rolled up.
