A pronounceable username is one that reads naturally when spoken out loud — it doesn't have to be a real dictionary word, just something your mouth can say without stumbling over a random string of consonants.
Pronounceable handles are easier to remember, easier to say to someone else, and easier to use as an actual brand or identity — which is exactly why buyers pay more for them than for an equally-short but harder-to-say combination.
There's no formal test — it's simply whether it reads naturally to most people. This is one of the factors covered in what makes a username valuable alongside length and letter/digit composition.
No — it just has to read naturally when spoken. "Zex" isn't a dictionary word but is still pronounceable; a random consonant cluster typically isn't.
