A pseudoword is a real term in language research for a pronounceable nonword. That gives the domain exceptionally precise uses in phonics assessment, psycholinguistics, reading instruction, language models and word-generation software.

Its value to founders is an immediate technical concept; to investors, a compact scientific-linguistic term with identifiable professional buyers, albeit a specialist audience.
