What is Anglish?
Anglish is a kind of English which prefers native words over those borrowed from foreign languages. Anglish is linguistic purism applied to English. For example: Dictionary > Wordbook Famous > Nameknown Native > Inborn Decide > Choose Computer > Reckoner This is achieved by simply choosing to use a native word over a borrowed word, or if there is no modern native word for a given concept, Old English words can be revived and updated to modern spelling and phonology to be used for a modern meaning.
Using the example that YouTuber Rob Words used, here is the preamble to the US Constitution in modern English vs Anglish.
