How these were scored

Every suggestion above pairs slack 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.
