IPA: /əˈlæn.tɔɪk/

Relating to a specific membrane in the developing embryo that helps in waste removal and gas exchange.
The allantoic fluid plays a crucial role in the development of the embryo.
Allantoic is derived from "allantois" (from Greek "allantois", meaning sausage or sausage-like), which refers to a membranous sac in embryos that stores waste. The suffix "-ic" (meaning pertaining to) indicates that it relates to the allantois. Thus, allantoic means pertaining to the allantois or the allantoic sac.
Think of the 'allantois' as a 'sac' that stores waste in embryos, and remember that 'allantoic' means something related to that sac.
