severally

This term is primarily used in legal and formal contexts to describe obligations or liabilities that are assigned to individuals independently. It is most frequently encountered in the phrase "jointly and severally," which indicates that a group is collectively responsible for a debt, but each individual member is also fully responsible for the entire amount on their own.

In common daily conversation, "severally" is rarely used and would sound unnaturally archaic or overly technical. Speakers typically substitute it with "individually," "separately," or "each" to avoid the legalistic tone associated with this adverb.
