Language is a system that consists of the development, acquisition, maintenance and use of complex systems of communication, particularly the human ability to do so; and a language is any specific example of such a system.
Henry Drummond: Language is a poor enough means of communication. I think we should use all the words we've got. Besides, there are damned few words that anybody understands!
Inherit the Wind (1960 film), Jerome Lawrence and Robert Edwin Lee
There are solar panels that covert sunlight directly to electricity, and there are others that absorb the sun's rays for hot water. EU-funded researchers have made progress on a solar thermoelectric generator that generates electricity from the sun's heat.
