解説 Definition
sept は September(9月)の略として使われることがある表現です。正式な英単語というより、メモや日付欄などで見られる短い表記です。

覚え方のコツ Memory Tip
September を先頭4文字に縮めた略記で、日付欄やメモでは Sept. の形が一般的。sept 10 のように数字の前に置かれる。語頭 sept- はラテン語 septem「7」に由来し、古代ローマ暦で3月から数えて7番目だった月が、現在の9月になった歴史と結び付ける。
Treat sept as a shortened written form of September, not normally as the full name of the month. You may see Sept. 10 on a schedule, calendar, or form; capitalization and a period are common in edited text, although compact systems vary. The opening sept- comes from Latin septem, meaning “seven.” September had that name because it was the seventh month in an early Roman calendar that began in March. Keeping both facts together—sept means seven historically, but September is month nine today—makes the abbreviation easy to recognize.

sept の語源・成り立ち Etymology
ラテン語 septem(7)に由来。古代ローマ暦では3月が年初だったため、9番目ではなく「7番目の月」という意味だった。関連語: septet(七重奏)、septennial(7年ごとの)。暦の改変で順番がずれたまま名前だけ残った。
Sept is a shortening of September. September comes through Old English and Latin September, based on Latin septem, meaning “seven.” In an early Roman calendar, the year began in March, so this month occupied the seventh position. January and February were later placed before March, shifting September to ninth place while its established name remained. The abbreviation is commonly written Sept. in English date notation.
