Page "Constructed script" Paragraph 2

All scripts, including traditional scripts such as the Chinese or the Arabic script are human creations.

However, scripts usually evolve out of other scripts rather than being designed by an individual.

In most cases, alphabets are adopted, i. e. a language is written in another language's script at first, and gradually develops peculiarities specific to its new environment over the centuries ( such as the letters w and j added to the Latin alphabet over time ).

Construction of a script entails that the author is aware of at least one writing system already.

Otherwise, the invention would not just comprise a script, but the concept of writing itself.

Therefore, a constructed script is always informed by at least one older writing system, making it difficult in some cases to decide whether a new script is simply an adoption or a new creation ( for example the Cyrillic and the Gothic alphabets, which are nearly identical to the Greek alphabet but were nevertheless designed by individual authors ).
