The amnionic fluid provides a protective cushion for the developing fetus.
Amnionic is derived from "amnion" (from Greek "amnion", meaning membrane surrounding the fetus) and the suffix "-ic" (meaning pertaining to). The word "amnionic" refers to something that is related to the amnion, the protective membrane surrounding a developing embryo.
Think of the 'amnion' as the protective 'membrane' around a fetus, and remember that 'amnionic' means pertaining to that membrane.
