The quality or state of being well-furnished or fully equipped with necessary furnishings and items.
From furnish (Old French fournir) + -ness (Old English suffix indicating a quality or state), creating an abstract noun describing the condition of being furnished.
Words ending in -ness are English's favorite way to turn adjectives and verbs into abstract qualities—'furnishness' is rare, but it perfectly captures the idea of 'the completeness of being outfitted.'
