SUBINFEUDATEsubinfeudate (s[schwa]b-in-fyoo-dayt), vb. Hist. (Of a subvassal) to grant land to another, who then holds the land as the grantor’s vassal rather than as the vassal of the grantor’s superior.
¡ª Also termed subinfeud (s[schwa]b-in-fyood).
¡°[A] more common method of obtaining the annual quota of knights was to subinfeudate portions of the baronial lands to individual knights in exchange for their obligations to spend a fixed portion of time annually in the king’s or baron’s service. A knight who so received a portion of a baron’s land would hold of his baron in much the same way as the baron held of the king.¡± Thomas F. Bergin & Paul G.
