the.com/vassal

a medieval middleman who swore loyalty upward and squeezed everyone downward.

means A person in feudal society who pledged loyalty and service to a lord in exchange for protection and the right to hold land.

from From the Old French 'vassal,' borrowed into Medieval Latin as 'vassallus,' both reaching back to a Celtic root meaning 'young man' or 'servant' — a cousin of Welsh 'gwas,' meaning 'servant' or 'youth.' So buried in this lofty title of feudal rank is the humbler idea of a lad in someone's service, the boy who fetched and carried before he ever swore an oath.
