Literally: “fern plant”
The story of the word
The Greeks named the fern after the feather. πτερίς comes straight from πτερόν, wing or feather, because a frond looks like one, so the same syllable opens pterodactyl and pterosaur. English speakers drop the p, which is why the word starts with a silent letter nobody pronounces. Botanists now treat pteridophyte as a convenience label rather than a single family tree.
