Color code
In our language journey, pronouns and nouns are ink blue. Highlights and mapping extents are forget-me-not, blue. We avoid color red, for the adverse associations that prescriptive opinion on language may bring. ■→More

Language form
We always need to know the language and the context, to see what the language form denotes: a picture of a cat is not a cat. To work on language form and syntax, we can use virtual words. We have two invented verbs, bimmo and thimo, and two invented nouns, phimo and rheemo. We use them only if and when we like. ■→More
