Historical definition
Aerdadi are corporeal spirits living in the air.
Meaning
The apparent tension between “spirits” and “corporeal” is part of the historical classification. The entry assigns these beings a dwelling place and a bodily character rather than treating every spirit as wholly without body. It is useful to retain both features. Replacing the expression simply with “air” would erase the beings described; replacing it with “incorporeal spirit” would reverse its stated qualification.
Use in the book
Compare Anachmus, expressly called incorporeal, and the fire-associated Æthnici. The contrasting descriptions show that the dictionary differentiates spirits by embodiment, appearance and habitat.
