The word "Rahonavis" is a genus of dinosaur and does not have a widely accepted etymology or meaning in a specific language. It is derived from the Greek word "rachis", meaning "spinal column" or "backbone", and "avis", meaning "bird". The name "Rahonavis" was coined by paleontologist Luis Chiappe and colleagues in 1998 for a bird-like dinosaur discovered in Madagascar, and it signifies its bird-like characteristics. However, it is important to note that the exact origin and meaning of the word may vary depending on the intentions of its namers.
