Affiliate Disclosure

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.

Stay impactful,

A Brief History of Our Alphabet

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

The history of our modern alphabet is a fascinating journey that spans several millennia and cultures. It’s commonly referred to as the Latin or Roman alphabet, and here’s a brief overview of its evolution:

  1. Phoenician Alphabet (circa 1050 BCE): The story begins with the Phoenician alphabet, one of the oldest writing systems known to use a one-to-one correspondence between sounds and symbols. This Semitic alphabet had about 22 consonants, but no vowels, and was primarily used for trade.
  2. Greek Alphabet (circa 800 BCE): The Greeks borrowed and adapted the Phoenician script. Crucially, they introduced vowels, making it one of the first true alphabets where each symbol represented a distinct sound (both vowel and consonant). The Greek alphabet had a significant influence on the development of other alphabets.
  3. Etruscan Alphabet (circa 700 BCE): The Etruscan civilization in Italy adapted the Greek alphabet to their own language. While Etruscan was largely replaced by Latin, their version of the alphabet was a key predecessor to the Roman one.
  4. Latin Alphabet (circa 700 BCE – Present): The Latin alphabet emerged from the adaptation of the Etruscan script. Ancient Rome used this alphabet, and it spread across Europe as the Roman Empire expanded. The original Latin alphabet did not contain the letters J, U, and W. These were added much later along with other modifications to suit different languages and phonetic needs.
  5. Modern Variations: Today, the Latin alphabet is the most widely used alphabetic writing system in the world. It has undergone various changes to accommodate different languages and sounds. For instance, English—among other languages—added letters like ‘J’, ‘U’, and ‘W’, while other languages incorporate additional characters like ‘Ñ’ in Spanish or ‘Ç’ in French.

This evolution reflects not just linguistic changes but also cultural and historical shifts, as the alphabet was adapted by different societies across centuries.
