Etymology: Caudally is a plain formation: the adverb "caudal" with the suffix "-ly" added, meaning "in the manner of" or "toward" the tail. The adjective "caudal" comes from Latin "cauda," meaning "tail," which has been traced back to a Proto-Indo-European root. The suffix has a longer ancestry of its own. The "-ly" ending descends from an old Germanic word for "body" or "form" (appearing in Old English as "-līc"), which gradually shrank into a simple marker that turns adjectives into adverbs. So "caudally" combines a classical root for tail with a native English ending that has been doing this job since the Old English period.
