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 the Letter I

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

The origins of I can be traced back to ancient Semitic languages, where a pictogram of a hand or an arm was used to represent a consonantal sound similar to /y/.

The Phoenicians simplified this pictogram into a linear form and named it “yod,” which meant ‘arm’ or ‘hand.’ Yod made a /j/ sound, somewhat akin to the English “y.”

The Greeks borrowed yod from the Phoenician alphabet, but they repurposed it to represent a vowel sound. They called this letter “iota,” which produced an /i/ sound, and it took the form of a single vertical stroke, the form we recognize today as I.

The Romans adopted the Greek alphabet and incorporated iota into their own alphabet, which would later become the Latin alphabet. Here, the character retained its name and form from the Greek script and continued to represent an /i/ sound.

It’s worth noting that, until the late Middle Ages, the letter I was used to represent both a vowel and a consonant sound, /i/ and /j/ respectively. It was not until the differentiation of I and J in the 16th century that I took on its exclusive role as a vowel in English.

In modern symbolic usage, I takes on several roles. In electrical engineering, I stands for electric current. In Roman numerals, I represents the number one. In information theory, I denotes information. In complex numbers, i is used to represent the imaginary unit.

From its ancient origins as a hand or an arm to its place in the modern English alphabet, the history of I offers a glimpse into the ways languages evolve and adapt over time. This journey highlights how written language, while serving as a record of human communication, is also a living, changing entity.
