Emily Dickinson Lexicon

GAR'NISH, v.t. [Fr. garnir; Arm. goarniça; Sp. guarnecer; It. guarnire, guernire; Norm. garner, garnisher, to warn, to summon. The latter sense is still used in law language, and it would seem that warn and garnish are from the same root, for warn, written in the Celtic manner, would be guarn.]

1. To adorn; to decorate with appendages; to set off. All within with flowers was garnished. Spenser.
2. To fit with fetters; a cant term.
3. To furnish; to supply; as, a fort garnished with troops.
4. In law, to warn; to give notice. [See Garnishee.]
