The dark green, sticky first stool passed by a newborn, sometimes seen in the liquor during labour.
The presence of meconium in the liquor prompted closer monitoring of the foetal heart.
Rarity runs from 0 (a word everyone knows) to 100 (almost never seen outside specialist or literary writing). Level is the word's real difficulty on the CEFR scale, from A1 to C2.
