How Fantasy Names Work: Sound Symbolism and Phonaesthetics

At a glance

Sound symbolism is a link between speech sounds and meaning that is not purely arbitrary. In experiments, most people match the made-up word bouba to a rounded shape and kiki to a spiky one, and a 2022 test across 25 languages found it in most of them. Studies of Pokémon names found that names with more voiced consonants such as b, d, g and z, and longer names, tend to belong to bigger, stronger characters. These are tendencies, not rules: no sound means 'evil' or 'elvish' on its own.

Classic experiment
Köhler's takete and maluma (1929, 1947); bouba and kiki (Ramachandran and Hubbard, 2001)
Biggest cross-language test
917 people, 25 languages: more than 70% of responses matched the expected pattern
Sounds linked with size
Voiced consonants (b, d, g, z) and the vowel a for big; the vowel i for small
Sounds in 'pleasant' words
l and m, smooth consonants, few clusters (Crystal, 1995)

Bouba, kiki and the shape of a sound

Most of the time the link between a word and its meaning is arbitrary. Trees are arbor in Latin, Baum in German and ki in Japanese. But researchers have long noticed exceptions, where a sound seems to suit what it names. This is called sound symbolism.[1]

Modern experiments began in the 1920s. Edward Sapir found that people tended to give the made-up name mal to a large table and mil to a small one. The psychologist Wolfgang Köhler showed people a rounded figure and a spiky one and asked which was takete. Most picked the spiky one, leaving the round shape for baluba (maluma in his 1947 edition).[1][2]

In 2001 V. S. Ramachandran and Edward Hubbard repeated the test with bouba and kiki, and the name stuck.[3][2] The largest check so far, published in 2022, tested 917 speakers of 25 languages using ten writing systems. On average more than 70% of responses matched bouba to round and kiki to spiky, and speakers of 17 of the 25 languages showed the effect clearly. Results varied from language to language, and an earlier study of Syuba speakers in Nepal found no effect at all.[2] So the effect is strong and widespread, but not universal.

Big, heavy and harsh: what the research says

A team led by Shigeto Kawahara studied every Japanese Pokémon name available in 2016. Names with more voiced obstruents (b, d, g, z) tended to belong to bigger, heavier Pokémon and to more evolved forms. Longer names went with bigger and stronger characters too. Names starting with high vowels such as i leaned towards smaller, lighter Pokémon, though that effect was small.[4] The authors link this to the 'frequency code' idea: low-pitched sounds suggest large things and high-pitched sounds small ones.[4]

The vowel link goes back to Sapir: many English speakers feel a is bigger than i.[4] But the pattern is not fixed for every language. In Korean ideophones, a is linked with smallness.[1]

Beauty has been studied too. David Crystal analysed lists of words people call beautiful, such as melody, velvet and gossamer. They favoured l and m and smooth, continuous consonants, used few consonant clusters, and often had three syllables with the stress on the first. Crystal was careful to say his sample was small, and that sound and meaning can't be fully separated: pleasant-sounding words usually mean pleasant things.[5]

Making a culture's names hang together

A single good name matters less than a set that sounds like it belongs to one people. Mark Rosenfelder's Language Construction Kit points out that Tolkien's Orkish relies on harsh consonants, while his Elvish is full of vowels, l and r.[6] Names like Gorbag and Shagrat lean on voiced consonants such as g and b; say them with k and p instead and they lose much of their menace.

Tolkien built his Elvish sounds on languages he loved. He wrote to W. H. Auden that Welsh names had fascinated him since childhood, and that finding a Finnish grammar made his own invented language heavily 'Finnicized' in sound and structure.[7]

The practical lesson is to choose a small set of sounds and syllable shapes for each culture and stick to it. That is writing advice rather than a research finding, but it follows from the evidence: readers notice patterns, and a name that breaks the pattern stands out.

Apostrophes and accents

Rosenfelder warns against adding apostrophes just to make a word look alien. Real languages use the apostrophe for very different things: a glottal stop in Hawaiian, a dropped letter in English, a syllable break in romanised Chinese. Because of that, it tells the reader nothing on its own. He gives similar advice on accents: give each mark one clear job and keep it.[6]

Tolkien's own spelling is the usual model. He spelt Quenya much like Latin and used two dots to show readers which vowels to sound separately, as in Eärendil, or that a final e is pronounced, as in Manwë.[6][8]

What is proven, and what is just advice

  • Well supported: most people, across many languages, link bouba-type words with round shapes and kiki-type words with spiky ones.[2]
  • Supported, but varies by language: voiced consonants and the vowel a suggest size and weight; i suggests smallness.[4][1]
  • Writing advice: keep each culture's sounds consistent, and don't use apostrophes or accents without a reason.[6]
  • Myth: that 'cellar door' has been shown to be the most beautiful phrase in English. It is an old claim that Tolkien repeated in a 1955 lecture. The lexicographer Grant Barrett traced it back to the early 1900s, long before Tolkien, and nobody has ever tested it. C. S. Lewis later noted that spelling it Selladore makes a lovely name.[9]

Sound symbolism nudges readers; it does not decide for them. A villain called Lirameli can still be terrifying if the story makes him so.

Frequently Asked Questions

What is the bouba/kiki effect?
It is the tendency to match the made-up word 'bouba' with a rounded shape and 'kiki' with a spiky one. A 2022 study of 917 people speaking 25 languages found that more than 70% of responses followed this pattern on average, though the strength varied between languages.
What makes a name sound evil?
There is no fixed rule, but research links voiced consonants such as b, d, g and z with size and heaviness, and fantasy writers often give villains short names with harsh consonants and back vowels, like Tolkien's orcs Gorbag and Shagrat. Context still matters more than sound.
Why do fantasy names have apostrophes?
Usually to make a name look foreign. Language inventors such as Mark Rosenfelder advise against it unless the apostrophe stands for a definite sound, such as a glottal stop, because real languages use it in so many different ways that it tells the reader nothing.
