Cnidiarian is the word for the phylum of jellyfish and sea anemomes. Some of the requirements to make it into the Cnidaria Phylum are possessing radial symmetry, having no nervous system or head but having a nerve net, and possessing nematocysts (which are stinging cells unique to cnidarians). Nematocysts are also called cnidea, which likely is the basis of the meaning of the name Cnidaria.
Cnidarian means any creature ( basically jelly fish ) who possesses stinging cells to capture prey that are called cnidnocytes.
