I recently noted that Theda can be a nickname for Theodora and Theodosia. I like it because I dislike Dora, but I am not sure I like it better than Thea. WDYT?
I don't really like it, possibly because I've heard 'theta' more often, so the D seems awkward.I'd prefer Thedra as a NN for Theodora or Thea as a NN for Theodosia.
I don't really like it. It is harsh and makes me think of spiders for some reason. There was a famous actress with that name many many years ago but I can't remember her surname now. Thea is better but I also don't really like it. Dora is also better but again I don't care for it.
