Esnes, a word that is now considered to be obsolete, is defined as a male servant or a serf in feudal times. However, there are several other words that can be used in place of esnes in modern English language. Some of the synonyms for esnes include vassal, bondman, retainer, thrall, villein, and serf. These words denote someone who is obligated to serve their master or lord, and has limited freedom and access to resources. Although the use of esnes may have declined, the concept of servitude and feudal hierarchy is still examined and explored in literature and media today.
