the ordinal form of the number zillion.
one of a zillion equal parts of a whole.
when my own mother, just 79, launched into talk of dying, i had to grind my teeth until my jaw ached in order not to say something rude as she ran through her burial plans for the zillionth time. by the time i packed to leave a few days later, i was in a state of high agitation, divided between my frustration at her focus on death and my uncertainty if i would ever see her again. “i love you,” i said as i bent over her wheelchair to kiss her goodbye. everydayhealth.com
