What does "oops" really mean?

“Oops, I did it again.”

“Oops, I did it again,” is the title of a year 2000, song by Britney Spears. It is a phrase about playfully and repeatedly misleading someone in a romantic sense.

The word, oops, is likely the most important word in the phrase. After all, “I did it again,” just doesn’t have the same spunk, kick, pizzazz. Oops is exactly what brings the joy of the joke, the humour of the play on words, and the hidden innuendos.

And for those of you who grew up following Britney you may have followed her journey from when she first sang, “I Feel for You.”, while she danced it up along her one-time love, Justin Timberlake, on television’s, “Mickey Mouse Club”; a show that was as innocent as girl guides. Then Britney’s fans became teens and pined over her and Justin’s true love relationship. Theirs was a pure, angelic love…until it all went bad.

“Oops, I did it again,” was the song that broke Britney’s virgin-like reputation into a hot, messy, sex symbol.

All thanks to that one, spunky word: Oops. Okay, maybe the provocative music video had something to do with it.

The phrase, oops, is an exclamation for a mistake, and the phrase literally means making the same “mistake” (leading someone on) a second time.

The etymology of oops shows that the word first appeared in writing around 1921.

Oops is considered a variation of the word whoops which is a shortened version of whoops-a daisy or oops-a-daisy.

These in turn were likely is pronounced versions of, up’s-a-daisy or upsy-daisy.

The phrase, Ups -a-daisy, comes from Up-a-daisy first recorded in 1711 in, A Journal to Stella, a work by Johnathan Swift which was an exclamation of encouragement for a child being lifted or getting up from a fall.

The daisy part is thought to be a corruption of lackaday, an archaic interjection that comes from the expression, “a lack the day”, used to express regret or sorrow. It was shortened over time, first appearing in its current form around 1695. Its use is now largely superseded by the adjective, lackadaisical.

“Alack the day” means “shame on the day”, or “alas for the day”. It originates from the contraction of ah, lack where lack had a broader idle English meaning of failure, fault, or shame. The full phrase was first used around the mid-1500’s. This phrase appears when Juliet’s nurse, in Romeo and Juliet, exclaims “Alack the day!” A regrettable or unfortunate situation.

Lack, found as far back as the 1300’s, meant absence, want, shortage, and deficiency. In old English, this word originally was lac, a word borrowed form Middle Dutch, lak, or Proto-Germanic, lek.

Lak is found as far back as the 12th century, meaning, “to be wanting” from lak – deficiency, fault, and “To be in want.”

Switching the word, oops, from Britney’s song back to older versions might go like this:

Lak, I did it again, I’m in want.

But alack the day

When I lack the luck

Lackaday – such regret such sorrow.

Yet, I’ll get up from this fall.

Ups-a-daisy

Whoops – I’ve fallen again.

In and out of love.

Now in Olde English!

Wealas! Hit dyde ic eft angean” – 1300’s
