Language is p（）in that it makes possible the construction and interpretation of new signals by its users. In other words, they can produce and understand an infinitely large number of sentences which they have never heard before.

The distinction between competence and performance was proposed by F. de Saussure.

Social changes can often bring about language changes.

The study of the ways in which morphemes can be combined to form words is called morphology.

Phonology

The study of meaning in language is known as semantics.

Modern linguistics is different from traditional grammar.

Both semantics and pragmatics study meanings.

Phonetics is different from phonology in that the latter studies the combinations of the sounds to convey meaning in communication.

In the study of linguistics, hypotheses formed should be based on language facts and checked against the observed facts.
