Broaden

broaden, extend, expand, enlarge

Mnemonic

You press your hand flat against the walls of a cramped room and shove them wide open, forcing them apart to broaden the entire space. Your hand keeps pushing outward—broader and broader—until the room stretches into a vast, echoing hall that seems to have no end.
Additional thoughts
Picture the physical strain in your palm as you push walls wide. The hand is the tool; wide is the result. Together they mean to broaden.
Quick recall
A hand forces walls wide apart to broaden the room.
