David Placek's Sound Symbolism Rules for Brand Names

The framework

Letters signal before words do

How to apply it

How do you use sound symbolism to name a company?

Placek's order: the promise, then the sounds, then the names.

1. 1

   Write the promise before any names.

   Placek starts clients on behavior and on how they will change the market. Skip that step and you end up with a list full of clouds, infos and seeks.

2. 2

   Turn the promise into two or three sound qualities.

   If buyers have to believe you can deliver, you need confident sounds. If the product is fast, speed goes on the list. His example brief to Lexicon's software asks for smoothness and speed.

3. 3

   Favor the letters that carry those qualities.

   From his interviews: V is alive and daring. B and P are reliable, and P, K and B together read reliable and fast. D and P are fast, and Z is really fast. S, Z and V are noisy, which is what Sonos wanted. X is fast and crisp.

4. 4

   Ration the letters that work against it.

   O and U are slow. A fast brand can carry one of them, but not many.

5. 5

   Keep the shape easy to process.

   Consonant, vowel, consonant, vowel is the pattern children learn language on. Rhyme and rhythm help memory: he rates DeepSeek a very good name for its rhyme and its doubled e's.

6. 6

   Sort the shortlist by sound, then check the meaning.

   Lexicon's software ranks candidates on the qualities you asked for. A name that would suit a healing, smooth cosmetic drops out of the top 20 for a fast brand. The linguistic and meaning checks come after.

Placek ties the letters to the promise:

He gives founders the same exercise: forget about naming for now and think about behavior. They may still end up with something like InfoSeek, but at least they have set standards.

Boundary conditions

When does sound symbolism mislead?

The second failure is built into the tool. When Lexicon's software, called Predict, sorts ten names by speed, it reads the letters and nothing else:

So meaning gets its own pass. Lexicon's linguist network checks names for negative meanings, cultural or political baggage, and events like a local disaster that nobody at head office would know about. About every third or fourth project, that check kills a name before the client ever sees it. Sound can put a name on the shortlist, and the meaning checks decide whether it stays.

Sound is one layer of a larger method. It sits in the invent step of Placek's naming process, after the team has defined what winning looks like and before trademark and implementation.

Where Placek discusses this

Where experts disagree

Where operators disagree: should a name sound right or say what you sell?

Both lists reward a name that is easy to say and remember. They split on meaning. A brand that sells through search and word of mouth gains from a name that says what it is; a company entering a crowded category where every rival sounds descriptive gains from a name that sounds like its promise.
