Every suggestion above pairs probability with one of the 5,000 most common .com domain prefixes or suffixes. Each compound is then scored on three things naming agencies care about:
Sound symbolism — Yorkston and Menon's 2004 Stanford study showed front vowels make products feel smaller and faster. V is the most alive letter in English (Vercel, Corvette, vibrant). Z and S are noisy attention-getters (Sonos, Azure).
Processing fluency — familiar morpheme fragments ("ver", "cel", "son") get processed faster by your brain and feel more natural even when the full word is invented. We give credit for these.
Compound multiplier — two real words put together (Windsurf, BlackBerry, PowerBook) create 1+1=3 associations. We tag these so you can spot them instantly.
