A skill is the ability to carry out a task with pre-determined results often within a given amount of time, energy, or both.

Skills can often be divided into domain general and domain-specific skills.

Language is the ability to acquire and use complex systems of communication, particularly the human ability to do so, and a language is any specific example of such a system.

The scientific study of language is called linguistics.

Thinkers such as Rousseau have argued that language originated from emotions while others like Kant have held that it originated from rational and logical thought.

20th-century philosophers such as Wittgenstein argued that philosophy is really the study of language.

Major figures in linguistics include Ferdinand de Saussure and Noam Chomsky.
