fourteenthly

This term is an ordinal adverb used exclusively for sequencing a long list of points, arguments, or steps. It is extremely rare in natural speech and is typically confined to highly structured, formal legal documents, academic treatises, or exhaustive lists where precise enumeration is required to maintain logical order.

Because of its length and rhythmic clunkiness, most writers avoid it in favor of simpler transitions like "Fourteenth" or "Finally." Using it in a casual or semi-formal context often appears pedantic or unnaturally stiff.
