seventhly

This term is used exclusively as an ordinal adverb to sequence a list of points or arguments. It is characteristic of highly formal, legalistic, or academic writing, often appearing in structured lists where a writer is meticulously enumerating a long series of reasons or conditions.

In modern conversational English, "seventhly" is rarely used because lists of this length are typically broken up into bullet points or simplified using "finally" or "lastly" once the sequence becomes cumbersome. Using it in a casual setting may sound overly stiff or intentionally pedantic.
