139. Describe communicative competence. Communicative competence is the ability to achieve communicative goals in a socially appropriate manner. It is organized and goal-oriented, i.e. it includes the ability to select and apply skills that are appropriate and effective in the respective context.
140. Describe linguistic competence. In linguistics, linguistic competence is the system of unconscious knowledge that one knows when they know a language. It is distinguished from linguistic performance, which includes all other factors that allow one to use one's language in practice.
141. Describe socio-linguistic competence. Sociolinguistic competence can be defined quite simply as knowing and understanding how to speak given the circumstances you are in such as the status of participants, the purposes of interactions, and the norms or conventions of interactions. Sociolinguistic competence also refers to the ability to select topics that are appropriate for a communicative event. For example, expressing strong views about politics and religion over dinner is generally avoided. This rule is also moderated depending on the relationship between the guest and the host.

The concept of "sociocultural competence" involves the ability to use specific information about nation, speech etiquette knowledge and communication technology in order to achieve mutual understanding with other culture bearers. Sociocultural competence includes knowledge about values, beliefs, behavior patterns, customs, traditions, language and cultural achievements peculiar to society.

Reasons for learning language have been different in different periods. In some eras, languages were mainly taught for the purpose of reading. In others, it was taught mainly to people who needed to use it orally. These differences influenced how language was taught in various periods. Also, theories about the nature of language and the nature of learning have changed. However, many of the current issues in language teaching have been considered off and on throughout history.
