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,

  2. Vowel use: U is one of the five traditional vowels in English. It can represent different sounds, including /uː/ as in “true,” /ʌ/ as in “cup,” and /juː/ as in “cute.”
  3. Word construction: U is often used in the construction of negative prefixes, such as “un-,” “under-,” “uni-,” and “ultra-,” all of which have Latin or Old English origins.

Its role in prefixes denotes its significance in word formation, and its various pronunciations showcase the flexibility of English phonetics. Despite its relative rarity, U undoubtedly brings a unique flavor to the language.

A Brief History of the Letter U

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

The letter U originated from the Semitic letter ‘waw’, which was also the origin of the modern letters F, Y, W, and V. This character represented a range of sounds in Semitic languages, including /w/, /v/, and /u/.

The Greeks adopted this letter into their alphabet as “upsilon” to represent the vowel sound /u/.

In the Roman alphabet, the Greek upsilon was adapted into the character V, which was used to denote both the vowel /u/ and the semivowel /v/. This character, visually identical to our current letter V, served a dual purpose, encapsulating both sounds. This lack of distinction between /u/ and /v/ persisted throughout the Latin language’s history, as Latin did not phonetically differentiate these sounds.

However, as Latin evolved into Old English during the medieval period, distinctions began to emerge between these sounds. Still, the differentiating point was often based on the character’s position in the word rather than a change in the character itself. The /u/ sound began to be represented as a distinct letter only in the late Middle Ages, with the character V being used for /v/ and U for /u/.

Interestingly, U was the last letter added to the English alphabet. Before its inclusion, the alphabet ended in V, and U didn’t find its place until print language was standardized. The modern shape of U, distinct from V, can be attributed to the French, who altered the form during the late medieval period.

From its early days on a Phoenician stone to its modern use in digital communication, the journey of the letter U is a fascinating testament to the evolving nature of language and writing systems. It is a clear example of how distinct characters can emerge from the same origins to serve different linguistic needs over time.
