Over the hill is an idiom that has been in use at least since the 1900s. We will examine the meaning of the phrase over the hill, where it came from and some examples of its use in sentences.
Over the hill is a phrase that describes someone old, someone worn out, someone who is past his prime. The idea is to think of one’s life as a hill. At the top of the hill, one is in his full prime and at the height of his attractiveness, power and ability. As life progresses, one descends the hill into old age. Once one is over the hill, he is past his prime. Calling someone over the hill is considered an insult. Surprisingly, the oldest known use of the idiom is 1950. Over the hill is rendered without a hyphen, unless it is used as an adjective before a noun as in over-the-hill.
