King James Dictionary [1]

Liege, a. L. ligo, to bind Gr. to bind, to bend a withe.

1. Bound by a feudal tenure obliged to be faithful and loyal to a superior, as a vassal to his lord subject faithful as a liege man. By liege homage, a vassal was bound to serve his lord against all, without excepting his sovereign or against all, excepting a former lord to whom he owed like service. 2. Sovereign as a liege lord. See the noun.

Liege, n. supra.

1. A vassal holding a fee by which he is bound to perform certain services and duties to his lord. 2. A lord or superior a sovereign.

Note. This is a false application of the word, arising probably from transferring the word from the vassal to the lord the lord of liege men, being called liege lord.
