Let’s turn our attention from the trees and the forests up to the heavens! In this post we consider names with linguistic roots in the celestial.
Stars
We’ve talked about Stella on the blog before, as an example of a name which many people think is modern, but which has actually been in use since at least the 15th C. It’s identical with the Latin word for ‘star’.
The origin of the Biblical name Esther is disputed, but one possible origin is the Persian word for ‘star’. This is a canonical example of a Protestant name, coming into use in the 16th C in French, Dutch, and English contexts.
The sun
Old Breton sul ‘sun’ (related to Latin sol) was a common prototheme in compound Breton names. We have examples of Sulhoiarn, Sulwal, and Sulwored (coming out in the next edition), as well as the monothematic name Sulon.
Next we have another Biblical name, Sampson, deriving from a Hebrew word for the sun. This name was surprisingly popular in France and England in the 12th century, though it was used sporadically in other times and places.
In this context let’s include names relating to dawn and sunrise: Orienta and Aurisma are both found in early 9th C France, and have etymological connections with dawn.
The heavens
The heavens generally are the root of two masc/fem pairs of names of Latin origin: Celeste and Celestus, and their derivatives Celestina and Celestine
Gods and goddesses
Lastly, we have two names which are connected to celestial phenomenon via the name of a god or goddess. The popular Welsh name Llywellyn derives from two god names, the second being the name of a sun god perhaps related to Apollo. The feminine name Tamar has two distinct origin; the examples we have so far represent the Biblical name of Hebrew origin, but the name also occurs in Georgia as the name of a sky goddess.
