Synonym: Fine, Beautiful. When used as a word of praise, fine (being opposed to coarse) denotes no "ordinary thing of its kind." It is not as strong as beautiful, in reference to the single attribute implied in the latter term; but when we speak of a fine woman, we include a greater variety of particulars, viz, all the qualities which become a woman, breeding, sentiment, tact, etc. The term is equally comprehensive when we speak of a fine garden, landscape, horse, poem, etc.; and, though applied to a great variety of objects, the word has still a very definite sense, denoting a high degree of characteristic excellence. Origin: F. Fin, LL. Finus fine, pure, fr. L. Finire to finish; cf. Finitus, p.p, finished, completed (hence the sense accomplished, perfect) See Finish, and cf. Finite.
