beau·ti·ful (bytə-fəl)
Share:
adj.
1. Having qualities that delight or appeal to the senses and often the mind.
2. Excellent; wonderful: hit a beautiful shot from the tee.
interj.
Used to express approval or delight.

beauti·ful·ly adv.
beauti·ful·ness n.

Synonyms: beautiful, lovely, pretty, handsome, comely, fair1
All these adjectives apply to what excites aesthetic admiration. Beautiful is most comprehensive and applies to mental appreciation as well as sensual delight: a beautiful child; a beautiful painting; a beautiful mathematical proof. Lovely also has wide application but stresses sensual enjoyment or emotional response over critical faculties: a lovely fragrance; the lovely feel of silk; greeted us with a lovely smile. What is pretty is beautiful in a delicate or graceful way: a pretty face; a pretty song; a pretty dress. Handsome stresses poise and dignity of form and proportion: a handsome, oak-paneled library. "She is very pretty, but not so extraordinarily handsome" (William Makepeace Thackeray).
Comely suggests wholesome physical attractiveness: "Mrs. Hurd is a large woman with a big, comely, simple face" (Ernest Hemingway).
Fair emphasizes freshness or purity: "In the highlands, in the country places, / Where the old plain men have rosy faces, / And the young fair maidens / Quiet eyes" (Robert Louis Stevenson).
