Where does speech come from? Why are there different languages? Why do languages
come and go?
"Language is the friendliest of the things from which
we cannot escape."
- Mason Cooley, U.S. aphorist
One characteristic that sets humans apart from other species
is the use of spoken language. People communicate thoughts and
feelings through the use of signs and words.
The science of language is called linguistics. Linguists study
the psychological processes involved in the use of language; the
development of linguistic capacities in children; social and cultural
factors in language use, variation and change; how speech sounds;
and the biological bases of language in the brain.
