秒
解説 Definition
sec は second（秒）の略で、「秒」を表すくだけた表記です。会話やメモでは使われますが、正式な文書では second と書くのが一般的です。
Sec is an informal abbreviation of second when referring to a unit or very short period of time. It appears frequently in conversation, notes, instructions, and compact measurements, while second is generally preferred in formal prose.
覚え方のコツ Memory Tip
sec は second の先頭3文字を取った略で、会話の「Wait a sec.」やメモ、時間表示で使うくだけた形。正式な文章では second を選ぶ。数値の後では「5 sec」のように単位記号風に無変化で書く場合と、会話的に secs と複数形にする場合がある。
Sec is simply the first three letters of second, so connect it directly with the time unit. The most useful conversational phrase is Wait a sec, meaning “wait for a very short time,” not necessarily an exact measured second. In notes and technical labels, a number may be followed by sec, as in 5 sec, with the abbreviation treated like a unit symbol. Informal writing may also use the plural secs. Choose the full form second or seconds in formal prose unless a required style guide permits abbreviations.
例文

Hold the button for five sec.

sec の語源・成り立ち Etymology
secはsecondの略で、語源はラテン語secundus「次に来る」。時計ではラテン語句secunda minuta「2番目の細分」が縮まり、「分の次の単位」つまり秒を表すようになった。関連語はsecond、sequence。
Sec is a modern shortening of second. Second comes through French from Latin secundus, meaning “following” or “next.” The time sense developed from the Medieval Latin expression secunda minuta, the “second small division” of an hour after the first division into minutes. Sec does not have a separate ancient origin; it was formed by clipping the spelling of the established English word second.
