Some names lodge themselves in memory after a single exposure. Others require years of advertising spend before they feel familiar. The difference is rarely luck — it's linguistics, cognitive science, and a few principles that have been studied extensively since the 1970s. Understanding them won't write your name for you, but it will help you recognise a good one when you find it.
The fluency effect: easy to process, easy to trust
Cognitive fluency is the ease with which the brain processes a piece of information. Decades of research show that things which are easy to process feel more true, more familiar, and more likeable — even when the content is identical to a harder-to-process alternative.
For brand names, this translates directly: names that are easy to pronounce are rated as more trustworthy and more likely to succeed than names that are difficult to pronounce — even by people who are told the study is about fluency and should know better. This isn't a bias to be corrected; it's a feature of how human memory works, and smart naming uses it deliberately.
Sound symbolism: letters that carry meaning
Individual sounds carry associations that transcend language. The hard "k" and "t" sounds convey speed, precision, and sharpness — think Kodak, Kit, TikTok. Soft vowels and nasal consonants ("m," "n," "l") suggest warmth, softness, and approachability — Monzo, Numi, Lullaby. This effect, called sound symbolism, has been replicated across dozens of languages and cultures.
You can use it consciously. A cybersecurity company that wants to project reliability and precision should probably avoid soft, rounded sounds. A children's wellness brand that wants to project warmth should probably avoid hard stops. Neither is a rule — but knowing the associations lets you make deliberate choices instead of accidental ones.
The bouba/kiki effect and visual brand alignment
In 1929, the psychologist Wolfgang Köhler asked participants to assign two nonsense words — "bouba" and "kiki" — to two shapes: one rounded, one spiky. Nearly everyone across all cultures assigned "bouba" to the round shape and "kiki" to the spiky one.
The implication for branding is real: your name carries an implied shape, and that shape either reinforces or contradicts your visual identity. If your logo is rounded and warm but your name is hard and angular, there is a subconscious mismatch that slightly undermines both. Alignment between name sound and visual identity is one of the less visible reasons some brands feel cohesive and others feel slightly off.
Distinctiveness beats descriptiveness for long-term recall
Memory research consistently shows that distinctive, unusual items are better remembered than typical ones — a phenomenon known as the von Restorff effect, or the isolation effect. Applied to brand names: a name that stands out from the noise of its category is more likely to be recalled than one that blends in, even if the blending-in name is technically more accurate.
This is the deepest argument against descriptive names. "Fast Delivery Co" tells you exactly what they do but competes with every other name in the same territory. "Hermes" (the Greek messenger god) tells you nothing about logistics but is distinctive, culturally rich, and impossible to confuse with anyone else in the space.
Repetition and the mere exposure effect
People rate stimuli they've been exposed to before as more positive — even when they don't consciously remember the exposure. This is the mere exposure effect, and it explains why brand advertising that doesn't seem to "work" in the short term often quietly builds preference over time.
For name selection, the implication is that names with repeated sounds or internal rhyme (Coca-Cola, Kit Kat, Dunkin') exploit this effect from the moment of first encounter. Every repetition of the sound pattern is a micro-dose of familiarity, and familiarity is a precursor to trust.
What to do with all of this
You don't need a linguistics PhD to apply these principles. When evaluating name candidates, ask: Is this easy to say? Does the sound match what I want people to feel? Is this name distinctive enough to stand out from everything else in this space? Does it align with how my brand looks and feels visually?
A name that scores well on most of these criteria will have a natural advantage — not because of magic, but because it works with how human cognition actually functions rather than against it. That's the most durable edge a name can have. Our brand name generator applies these principles to produce names that are short, distinctive, and built to stick.
