Diem

Diem is the accusative singular form of the Latin noun dies, meaning “day.” In Latin sentences, diem is used when the day is the direct object of a verb, and the word appears in many phrases borrowed into English. The most famous is carpe diem.

Carpe diem originates with the Roman poet Horace; the line carpe diem, quam minimum credula postero, is commonly rendered as “seize the day, put very little trust in tomorrow.” While Horace wrote in Latin in his Odes, the phrase has become a widely cited motto in modern culture, often interpreted as an encouragement to seize opportunities and live in the present.

In addition to carpe diem, the word diem appears in other Latin terms used in English, such as per diem, meaning “per day,” a common expression in business and travel to denote daily allowances or rates. In contemporary usage, carpe diem is frequently invoked in literature, film, and motivational contexts. It is sometimes celebrated as an uplifting reminder to value time, but it can also be criticized for promoting short-term thinking or imprudence if taken as a directive to disregard the future.

Linguistic note: diem is part of a broader Latin vocabulary for time and days, with dies (the base form meaning “day”) appearing in many related phrases and contexts. The enduring presence of carpe diem in English demonstrates how a compact Latin expression can shape cultural attitudes toward time and living.
