英語の原文(Wiktionary)
Borrowed from French gravité (“seriousness, solemnity; severity; (physics) gravity”), or from its etymon Latin gravitās (“heaviness, weight; seriousness; severity”), equivalent to grave (“serious”) + -ity (suffix forming nouns, especially abstract nouns). Gravitās is derived from gravis (“heavy; grave, serious”) (ultimately from Proto-Indo-European *gʷreh₂- (“heavy”)) + -tās (suffix forming feminine abstract nouns indicating states of being). The English word was first used figuratively, and gained the senses relating to physical qualities in the 17th century. Doublet of gravitas.
