title_body: How to classify the language of "Uncleftish Beholding"?
upvoted_answer: I wouldn’t personally call Anglish (that is, English without non-Germanic (or sometimes even non-Anglosaxon) vocabulary) a conlang. Taken at face value, it replaces English vocabulary 1:1 with coined words, which is basically the definition of a relex. Whether you want to consider relexes a subset of conlangs or an entirely different category (perhaps a subset of ciphers and codes) altogether is subjective.
  
  As a note, Anglish can also just be stylistic in nature — favouring germanic word stems over loaned ones where possible, but in the context of the essay you posted this is clearly not the case.
