Discover the fascinating history of human language-from its beginning as a single tongue spoken some 150,000 years ago to the estimated 6,000 languages spoken today.
Professor John McWhorter introduces the course by exploring two questions: What distinguishes the language ability of humans from the signaling system of animals, and when did humans first acquire language?
We look at evidence that language is an innate ability of the human brain, an idea linked to Noam Chomsky. But many linguists and psychologists see language as one facet of cognition rather than as a separate ability.
The first of five lectures on language change examines how sounds evolve, exemplified by the Great Vowel Shift in English and the complex tone system in Chinese.
Language change is not just sound erosion and morphing, but the building of new words and constructions. This lecture shows how such developments lead to novel grammatical features.
The meaning of a word changes over time. Silly first meant "blessed" and acquired its current sense through a series of gradual steps. Word order also changes: In Old English, the verb usually came at the end of a sentence.
The first language has evolved into 6,000 because language change takes place in many directions. Latin split in this way into the Romance languages as changes proceeded differently in each area where the Romans brought Latin.
As recently as Shakespeare, English words had meanings different enough to interfere with our understanding of his language today. Even by the 1800s, Jane Austen's work is full of sentences that would now be considered errors.
The first of four lectures on language families introduces Indo-European, which probably began in the southern steppes of Russia around 4000 BCE and then spread westward to most of Europe and eastward to Iran and India.
Linguists have reconstructed the proto-language of the Indo-Europeans by comparing the modern languages. Applying this process, we learn the Proto-Indo-European word for sister-in-law that was spoken 6,000 years ago.
Semitic languages assign basic meanings to three-consonant sequences and create words by altering the vowels around them. In Sino-Tibetan languages, a sentence tends to leave more to context than we often imagine possible.
