Weak Evidence for Word-Order Universals
A group of researchers at the Max Planck Institute for Psycholinguistics in Nijmegen, the Netherlands, has now found that word-orders in languages from different language families evolve differently.
The finding contradicts the common understanding that word-order develops in accordance with a set of universal rules, applicable to all languages.
Researchers have concluded that languages do not primarily follow innate rules of language processing in the brain. Rather, sentence structure is determined by the historical context in which a language develops.
Linguists want to understand how languages have become so diverse and what constraints language evolution is subject to. To this end, they search for recurring patterns in language structure.
In spite of the enormous variety of sounds and sentence structure patterns, linguistic chaos actually stays within certain limits: individual language patterns repeat themselves. For example, in some languages, the verb is placed at the beginning of the sentence, while with others it is placed in the middle or at the end of the sentence. The formation of words in a given language also follows certain principles.
Michael Dunn and Stephen Levinson of the Max Planck Institute for Psycholinguistics have analysed 301 languages from four major language families: Austronesian, Indo-European, Bantu and Uto-Aztecan.
The researchers focused on the order of the different sentence parts, such as "object-verb," "preposition-noun," "genitive- noun" or "relative clause-noun," and whether their position in the sentence influenced the other parts of the sentence.
In this way, the researchers wanted to find out whether the position of the verb has other syntactic consequences: if the verb precedes the object for example ("The player kicks the ball"), is the preposition simultaneously placed before the noun ("into the goal")? Such a pattern is observed in many languages, but is it an inevitable feature of how languages develop?
"Our study shows that different processes occur in different language families," says Michael Dunn. "The evolution of language does not follow one universal set of rules." For example, the "verb-object" pattern influences the "preposition-noun" pattern in the Austronesian and Indo-European languages, but not in the same way, and not in the other two language families. The researchers never found the same pattern in word-order across all language families.
