Hey fellow impactful ninja ?

You may have noticed that Impactful Ninja is all about providing helpful information to make a positive impact on the world and society. And that we love to link back to where we found all the information for each of our posts.

  • Most of these links are informational-based for you to check out their primary sources with one click.

  • But some of these links are so-called "affiliate links" to products that we recommend.

Why do we add these product links?

First and foremost, because we believe that they add value to you. For example, when we wrote a post about the environmental impact of long showers, we came across an EPA recommendation to use WaterSense showerheads. So we linked to where you can find them. Or, for many of our posts, we also link to our favorite books on that topic so that you can get a much more holistic overview than one single blog post could provide.

And when there is an affiliate program for these products, we sign up for it. For example, as Amazon Associates, we earn from qualifying purchases.

What do these affiliate links mean for you?
  1. First, and most importantly, we still only recommend products that we believe add value for you.

  2. When you buy something through one of our affiliate links, we may earn a small commission - but at no additional costs to you.

  3. And when you buy something through a link that is not an affiliate link, we won’t receive any commission but we’ll still be happy to have helped you.

What do these affiliate links mean for us?
  1. When we find products that we believe add value to you and the seller has an affiliate program, we sign up for it.

  2. When you buy something through one of our affiliate links, we may earn a small commission (at no extra costs to you).

  3. And at this point in time, all money is reinvested in sharing the most helpful content with you. This includes all operating costs for running this site and the content creation itself.

What does this mean for me personally?

You may have noticed by the way Impactful Ninja is operated that money is not the driving factor behind it. It is a passion project of mine and I love to share helpful information with you to make a positive impact on the world and society. However, it's a project in that I invest a lot of time and also quite some money.

Eventually, my dream is to one day turn this passion project into my full-time job and provide even more helpful information. But that's still a long time to go.

A Brief History of the Letter O

The story of the letter O has a rich and compelling history, beginning with ancient civilizations and carrying forward into the present day.

The letter O began its life as a hieroglyph that looked like a circular outline and represented the sound /ʕ/ in the Ancient Egyptian language

The Phoenicians adopted this character, keeping the circular shape but simplifying the design. They assigned it the sound /ʕ/ and named it ‘ayin,’ which translates to ‘eye.’

When the Greeks adopted the Phoenician alphabet, they repurposed ayin to represent a vowel sound. They called it ‘omicron,’ which means ‘small o,’ to differentiate it from the letter ‘omega,’ which was a long ‘o’ sound. Omicron was visually identical to our modern O, a testament to the enduring power of this simple design.

The Romans borrowed the Greek alphabet, including omicron, and adapted it to their own language to create the Latin alphabet. O retained its circular shape and vowel sound from Greek to Latin. It’s worth noting that O was the first vowel in the Latin alphabet, emphasizing its fundamental role in the language.

In modern usage, O has taken on a myriad of symbolic meanings beyond its role as a letter. In mathematics, O is used to represent the set of all whole numbers, also known as integers. In chemistry, O is the symbol for oxygen. In language, ‘O’ is sometimes used as a standalone exclamation or a poetic form of ‘oh.’ In pop culture, O often symbolizes a hug when used in the context of ‘XOXO,’ denoting ‘kisses and hugs.’

From an ancient hieroglyph to its position in the modern English alphabet, the journey of the letter O offers a compelling look into the evolution of written communication. Its simple, circular form and its foundational role as a vowel highlight the importance of design efficiency and linguistic necessity in shaping the alphabet.
