Good thing they avoided that. "Radix" is a much more common word, easier to clash with other same-named things, harder to search for.
I greatly disapprove of the fashion of naming projects with common words. Names like Flickr or Google or Linux or Inkscape are effortlessly unique. Names like Snowflake are self-defeatedly commonplace.
Sorry for nitpicking but "radical" is also used as a noun, particularly when looking for roots of an algebraic expression, as well as in chemistry (free radicals).
Certainly, a number of Latin adjectives turned into nouns in English, like radical, terminal, solid, tenant, etc. Same even happened to some verbs, like caveat or video.
But what you can expect from a language that allows one to tape a talk, or to circle back about an ask?
- "In botany, the radicle is the first part of a seedling (a growing plant embryo) to emerge from the seed during the process of germination.[1]"
