incĭens

Prægnans (from γενέσθαι, gnasci) denotes pregnancy quite in a general sense; gravidus, that of human beings; fœtus, fordus, inciens, that of animals, as with young; fœtus (from φύω) that of all animals; fordus or hordus (φοράς) that of cows; inciens (ἔγκυος) that of small animals, and particularly of swine. Varro, R. R. ii. 5. Quæ sterilis est vacca, taura appellatur; Quæ prægnans, horda. Gravida mulier is the physical and medical expression, like ἔγκυος; prægnans, the more select and decorous expression, something like ‘in a family way.’ (v. 226.)
