" gravidity "

[Adjective]  | "grav*id" | \ ˈgra-vəd \

1: pregnant

2: distended with or full of eggs

Origin: 1597 ;

 Borrowed from Latin gravidus, from gravis "heavy" + -idus, adjective suffix {mat|grave:2|};

  * Note : Latin adjectives with the suffix -idus regularly correspond to nouns ending in -or and/or verbs of the second conjugation, sometimes with a secondary verbal derivative with the inchoative suffix -ēsc-. The word gravidus does not fit this pattern and anomalously appears to be derived directly from a more basic adjective, though the grounds for such a process may be the existence of gravēscere "to become weighed down, become pregnant," from which gravidus may have been created by a sort of back-formation. On the other hand, gravidus is attested significantly earlier than gravēscere.;
