Emily Dickinson Lexicon

GRAND, a. [Fr. grand; Sp. and It. grande; L. grandis; Norm. grant. If n is casual, this word coincides with great. But most probably it belongs to the Class Rn. The sense is to extend, to advance; hence it signifies old, advanced in age, as well as great.]

1. Great; but mostly in a figurative sense; illustrious; high in power or dignity; as, a grand lord. Ralegh.
2. Great; splendid; magnificent; as, a grand design; a grand parade; a grand view or prospect.
3. Great; principal; chief; as, Satan our grand foe. Milton.
4. Noble; sublime; lofty; conceived or expressed with great dignity; as, a grand conception. In general, we apply the epithet grand to that which is great and elevated, or which elevates and expands our ideas. The ocean, the sky, a lofty tower, are grand objects. But to constitute a thing grand, it seems necessary that it should be distinguished by some degree of beauty. Elem. of Criticism.
5. Old; more advanced; as in grandfather, grandmother, that is, old-father; and to correspond with this relation, we use grandson, granddaughter, grandchild.
