Linguistic Competence By Noam Chomsky is somewhat similar to Saussure’s concept of language and parole.Competence, according to Chomsky, is the native speaker’s knowledge of his language, the system of rules he has mastered, his ability to produce and understand a vast number of new sentences.

Performance is the study of the system of rules; performance is the study of actual sentences themselves, of the actual use of the language in real-life situation. So the speaker’s knowledge of the structure of language is his linguistic competence and the way in which it is uses his linguistic performance.

Competence is, then, an underlying mental system, it underlies actual behavior, linguistic institution ability to analyze language, detecting ambiguities, ignoring mistakes, understanding new sentences, producing entirely new sentences. Whereas competence is a set of Principles which a speaker masters, performance is what a speaker does. The former is a kind of code; the latter is an act of encoding or decoding.

Competence concerns the kind of structures the person has succeeded in mastering and internalizing, whether or not he utilizes them, in practice, without interference from the many of the factors that play a role in actual behavior. For anyone concerned with intellectual processes, or any question that goes beyond mere date arranging, it is the question of competence that is fundamental. Obviously one can find out about competence only by studying performance, but this study must be carried out in devious and clever ways, if any successful result is to be obtained. In this ways the abstract, internal grammar which enables a speaker to utter and understand an infinite number of potential utterances is a speaker’s competence.

The Secrets To Linguistic Competence You Must Know

This distinction has caused a lot of arguments in current-day linguistics. Some socio-linguists regard it as an unreal distinction which ignores the importance of studying language in its social setting. They say that many of today’s grammars are based on unjustified assumptions a speaker’s competence rather on his performance. But the division is a useful one, if not carried to extremes. In an ideal situation, the two approaches should complement each other. Any statements concerning a speaker’s competence must ultimately be derived from data collected while studying his performance.

Although Chomsky’ competence/performance closely resembles Saussure’s langue/parole. Yet the main difference is that Saussure streets the sociological implications of langue, while Chomsky stresses the psychological implications of competence. These distinctions are also parallel to a distinction made between code and message in communications engineering! A code is the pre-arranged signaling system. A message is an actual message sent using that system.

The concept of linguistic competence, as introduced by Noam Chomsky, refers to the innate capacity of a human being to understand and produce language. This capacity is inherent and distinct from linguistic performance, which is the actual use of language in concrete situations.

Here’s a guide to understanding Chomsky’s concept of linguistic competence in a tabular format:

Aspect	Description
Definition	The inherent ability of an individual to understand and produce language, irrespective of actual language use.
Key Focus	Understanding the innate structure and rules of a language that a speaker knows.
Characteristics	– Universal among all humans. <br> – Independent of socio-cultural factors. <br> – Basis for language acquisition.
Contrast with Performance	While competence is about the knowledge of language, performance is the actual use of language in daily life.
Importance in Linguistics	Helps in understanding how language is processed and acquired, forming the basis for theories in linguistics.
Relation to Grammar	Involves knowledge of both the explicit and implicit rules of a language’s grammar.
Innateness Hypothesis	Suggests that linguistic competence is innate and genetically programmed in human beings.
Impact on Language Teaching	Influences methods and approaches in language teaching, emphasizing the understanding of underlying rules.

This table summarizes the key elements of Chomsky’s theory of linguistic competence, highlighting its significance in the field of linguistics and language education.

Conclusion

Noam Chomsky’s concept of linguistic competence has had a profound impact on the field of linguistics. It has significantly shaped our understanding of how language is acquired, processed, and used by humans. By delving into the various components of linguistic competence, we can appreciate the complexities and intricacies involved in our linguistic abilities. Understanding linguistic competence not only deepens our comprehension of language but also provides valuable insights into the human mind and its capability to acquire and utilize language effectively.

It was a concept introduced by Noam Chomsky in 1957. In a very brief way, we can say that linguistic competence resides in the ability to use sounds, forms, syntax and vocabulary correctly and appropriately. In this way, a person is linguistically competent if he or she conforms to the phonetic, morphological, syntactical and lexical rules of a language.

Linguistic Competence and Performance: Understanding How We Know and Use Language

Language is more than speaking words — it’s about knowing the system and using it correctly in real-world situations. In linguistics, this difference is explained by the concepts of linguistic competence, performance, and their extensions like communicative and sociolinguistic competence.

In this blog, we’ll explore:

• What is linguistic competence?

• What is performance?

• How do they differ? (with examples)

• How do communicative and sociolinguistic competence expand on Chomsky’s ideas?

🧠 What Is Linguistic Competence?

Linguistic competence refers to a speaker’s unconscious knowledge of their native language — including the rules of grammar, vocabulary, syntax, and phonology.

Coined by Noam Chomsky, it’s the “mental grammar” that allows someone to produce and understand sentences — even ones they’ve never heard before.

📌 Examples of Linguistic Competence:

• Knowing that “The dog chased the cat” is correct, but “Dog the cat chased” is not.

• Understanding how to form plurals (“cat” → “cats”, “bus” → “buses”).

• Recognizing that “goed” is incorrect, even if a child says it.

---

🗣️ What Is Linguistic Performance?

Performance is how people actually use language in real-life situations. It includes both correct and incorrect language use — slips, hesitations, and incomplete sentences.

Chomsky used this concept to separate the ideal knowledge of language (competence) from how it’s actually used (performance).

📌 Linguistic Performance Examples:

• Saying “I, uh, went to the… the movie thing yesterday.”

• Making a grammar mistake when nervous: “He go to school every day.”

• Mispronouncing a word while speaking fast: “liberry” instead of “library.”

🗨️ Communicative Competence: Beyond Grammar

Communicative competence was introduced by Dell Hymes in response to Chomsky’s focus on formal grammar. It includes not just linguistic knowledge, but also knowing how to use language appropriately in social contexts.

🎯 Key Areas of Communicative Competence:

1. Linguistic competence – Grammar, vocabulary, pronunciation

2. Sociolinguistic competence – Understanding context, roles, and cultural norms

3. Discourse competence – Organizing ideas in longer speech or writing

4. Strategic competence – Handling breakdowns in communication (e.g., asking for clarification)

---

🌍 What Is Sociolinguistic Competence?

Sociolinguistic competence refers to the ability to use and interpret language appropriately in different social situations. It’s about knowing:

• How to be polite or formal

• When to use slang or standard language

• Cultural expectations in greetings, requests, etc.

📌 Examples of Sociolinguistic Competence:

• Saying “Good morning, sir” in a job interview vs. “Hey dude” to a friend

• Using honorifics in Japanese (e.g., -san, -sama)

• Understanding that “How are you?” may not expect a detailed response

💡 Why These Concepts Matter

Understanding the distinctions among linguistic competence, performance, and communicative abilities is vital for:

• Language teaching and curriculum design

• Speech therapy and language assessment

• Sociolinguistic and psycholinguistic research

• Building AI language models (like me!)

📝 Summary Chart

In conclusion, linguistic competence by Chomsky highlights the innate knowledge of language that humans possess and its significance in language acquisition and use. By embracing this concept and incorporating it into language education, we can foster a deeper understanding of language structures and empower individuals to communicate effectively in diverse linguistic environments.
