splendid

Splendid means magnificently excellent. A splendid house, a splendid meal, absolutely splendid.

In British English it is also a warm exclamation of approval — Splendid! — which is slightly old-fashioned and cheerfully so. Splendid isolation is the fixed historical phrase for Britain's nineteenth-century foreign policy of avoiding alliances. Note splendour, the noun, spelled splendor in America; and that splendid describes both real grandeur and, in speech, simple satisfaction that a thing has worked out.
