English Designed for Kids

English vocabulary is designed to help children learn according to research led by the UK’s Lancaster University.

From obvious examples, like "woof" representing the sound of a dog to sounds with similar meanings having similar structures (for example, the "sl" sound at the beginning of a word often has negative properties as in "slime, slur, slum, slug"), English is full of hints for children.

An international team led by Professor Padraic Monaghan from the Department of Psychology at Lancaster University analyzed the sound meaning structure using statistical techniques from biology and genetics.

The research, published in the Philosophical Transactions of The Royal Society, shows that the structure of the vocabulary in English helps both children and adults.

He said: "Sounds relate to meaning for the words that children first encounter, addressing a critical question about how language is structured to aid learning.

"However, the later adult vocabulary is arbitrary, consistent with computational models of efficient language production and accurate language comprehension."

The debate about whether the sound of words contains information about meaning has continued for over 2,300 years.

This issue lies at the foundation of modern linguistics and psychology of language, which has been brought into stark relief by recent studies of sound symbolism where words actually sound like their meaning.

Sound symbolism has been suggested to be prevalent in language and necessary for language acquisition by children.
