Superlative form of graceful; the most elegant, smooth, or beautiful in movement or appearance.
From graceful + '-est' (superlative suffix); though standard modern English prefers 'most graceful,' this double-superlative persists in older or regional usage.
Comparing gracefullest to most graceful reveals how English is constantly shedding old suffixes—language evolves toward whatever is easier to say, which is why fewer people use '-est' on longer words.
