Which language of origin includes the words firmament, solar, and maternal?

The term "firmament," "solar," and "maternal" all derive from Latin roots, which places them within the Latin/Romance language family.

"Firmament" comes from the Latin word "firmamentum," meaning a solid structure or support, often used to refer to the sky or heavens.

"Solar" is derived from the Latin "solaris," which means "of the sun."

"Maternal" originates from the Latin word "maternalis," signifying something that is related to motherhood or mothers.

This strong association with Latin demonstrates that these words not only share a connection to a common linguistic ancestry but also reflect the depth of Latin influence on the English language, especially through the Romance languages that evolved from Latin.
