20 words that once meant something very different

Amazing how the changes came and we were unaware of it.

Words change meaning all the time — and over time. Language historian Anne Curzan takes a closer look at this phenomenon, and shares some words that used to mean something totally different.

Words change meaning over time in ways that might surprise you. We sometimes notice words changing meaning under our noses (e.g., unique coming to mean “very unusual” rather than “one of a kind”) — and it can be disconcerting. How in the world are we all going to communicate effectively if we allow words to shift in meaning like that?

The good news: History tells us that we’ll be fine. Words have been changing meaning — sometimes radically — as long as there have been words and speakers to speak them. Here is just a small sampling of words you may not have realized didn’t always mean what they mean today.

Squaring of even nos. made easy

Try squaring a 3 digit even no or a 4 digit even no. mentally. Oh yeah it’s hard. But what if we make it easy. What if for squaring a 3 digit no. you just need to multiply a 3 digit no with a two digit. Yeah! it would be far more easy. By following the given steps you can easily do so. Here you go : –

  1. Choose a no.
    Say 124.
  2. Divide the no by 2.
    Thus 124 / 2 = 62
  3. Multiply the original no by the quotient you got.
    Thus 124 * 62 = 7688
  4. Now the final step is to multiply the product by 2.
    Thus the desired answer is 7688 * 2 = 15376Enjoy your squaring guys 🙂 😀

Squaring 2 digit nos.

Want to square a two digit no. mentally ??
Here is the trick….

Steps:-

  1. Choose your no.
    Say 37.
  2. Add the units digit to the original no.
    Thus 37 + 7 = 44
  3. Multiply the sum by the tens digit of the original no.
    Thus 44 * 3 = 132
  4. Then take the square of the ones digit of the original no.
    Thus 7 * 7 = 49
  5. Add the tens digit of the square to the product you got earlier and then concatenate the ones digit to the sum.
    Thus 132 + 4 = 136. After concatenating the ones digit : –
    1369
  6. Thus then you will get your square.
    thus square of 37 is 1369.Enjoy your squaring now. 🙂
