Relating to, contained in, or involving the amnion or amniotic fluid; an alternate spelling or form of amniotic.
From amnion plus the adjectival suffix -ic. This variant exists alongside the more common 'amniotic' in medical literature.
Most doctors say 'amniotic' now, but amnionic survives in older medical literature and in some technical contexts—it's like how 'ox' and 'oxen' still exist even though we usually say 'cattle.'
