IPA: //ʌnˈlɛv.ənd//
KK: /ʌnˈlɛvənd/
A type of bread that is made without yeast or any substance that causes it to rise.
During Passover, many people eat unleavened bread as part of the tradition.
Unleavened → It is formed from "un-" (meaning not) and "leaven" (from Old English *leafian*, meaning to raise or ferment). The word "unleavened" means not raised or fermented, typically referring to bread made without leavening agents.
Think of 'not' ('un-') raising or fermenting ('leaven') — that's why unleavened bread is flat and does not rise.
