Etymology: "Rhizoidal" is formed from "rhizoid" plus the adjective suffix "-al". "Rhizoid" comes from Greek "rhiza", meaning root, combined with the suffix "-oid", meaning resembling or having the form of. So a rhizoid is something that resembles a root, and rhizoidal describes that form. The term is a technical coinage from botany, not an ancient word. Botanists use it for the thread-like structures on non-vascular plants such as mosses, liverworts and some algae, which anchor the organism to its substrate and absorb water and minerals but are not true roots, lacking the vascular tissue of real roots. Calling them "rhizoids" was a way of noting their resemblance to roots while marking the difference.
