 Syn: -- Old; primitive; pristine; antique; antiquated; old-fashioned; obsolete.
 Usage: -- Ancient, Antiquated, Obsolete, Antique, Antic, Old. -- Ancient is opposed to modern, and has antiquity; as, an ancient family, ancient landmarks, ancient institutions, systems of thought, etc.  Antiquated describes that which has gone out of use or fashion; as, antiquated furniture, antiquated laws, rules, etc.  Obsolete is commonly used, instead of antiquated, in reference to language, customs, etc.; as, an obsolete word or phrase, an obsolete expression. Antique is applied, in present usage, either to that which has come down from the ancients; as, an antique cameo, bust, etc. ; or to that which is made to imitate some ancient work of art; as, an antique temple. In the days of Shakespeare, antique was often used for ancient; as, “an antique song,” “an antique Roman;” and hence, from singularity often attached to what is ancient, it was used in the sense of grotesque; as, “an oak whose antique root peeps out; ” and hence came our present word antic, denoting grotesque or ridiculous.  We usually apply both ancient and old to things subject to gradual decay. We say, an old man, an ancient record; but never, the old stars, an old river or mountain. In general, however, ancient is opposed to modern, and old to new, fresh, or recent. When we speak of a thing that existed formerly, which has ceased to exist, we commonly use ancient; as, ancient republics, ancient heroes; and not old republics, old heroes. But when the thing which began or existed in former times is still in existence, we use either ancient or old; as, ancient statues or paintings, or old statues or paintings; ancient authors, or old authors, meaning books.
