Though I’d never call myself a proper linguist, I have had (ever since reading Bill Bryson’s Made In America, though the inclination probably predated that) an abiding interest in languages, grammars, and orthography.
I, like many children, invented “languages” when I was young, which was an exercise in substitution tables rather than the creation of a new grammar. Hell, I did it as recently as high school. The impulse to create new words and “languages” is universal, I think, though it may arise from different reasons.
