LANGUAGE
Language is communication by means of speaking, writing, or signing with our hands and is based on a system of symbols. Language is greatly varied throughout the world, but all languages share a common set of rules to keep them in order. The five rule systems of language are explained below.
(We can think of language as an iceberg: we see only the tip of the ice, but there is much more below the surface.)
Language is the ability to produce and comprehend spoken and written words; linguistics is the study of language.
Key Points that are easy to understand about language
- Grammar is a set of rules for generating logical communication.
- All languages have grammar, and native speakers of a language have internalized the rules of that language’s grammar.
- Every language has a lexicon or the sum total of all the words in that language.
- Phonetics and phonemics are the studies of individual units of sound in languages.
- Morphology is the study of words and other meaningful units of language.
- The syntax is the study of sentences and phrases, and the rules of grammar that sentences obey.
- Semantics is the study of sentence meaning; pragmatics is the study of sentence meaning in context.
Language is the ability to produce and comprehend both spoken and written (and in the case of sign language, signed) words. Understanding how language works means reaching across many branches of psychology—everything from basic neurological functioning to high-level cognitive processing. Language shapes our social interactions and brings order to our lives. Complex language is one of the defining factors that make us human. Two of the concepts that make the language unique are grammar and lexicon
1) Grammar
Because all language obeys a set of combinatory rules, we can communicate an infinite number of concepts. While every language has a different set of rules, all languages do obey rules. These rules are known as grammar. Speakers of a language have internalized the rules and exceptions for that language’s grammar. There are rules for every level of language—word formation (for example, native speakers of English have internalized the general rule that -ed is the ending for past-tense verbs, so even when they encounter a brand-new verb, they automatically know how to put it into past tense); phrase formation (for example, knowing that when you use the verb “buy,” it needs a subject and an object; “She buys” is wrong, but “She buys a gift” is okay); and sentence formation.

2) Lexicon
Every language has its rules, which act as a framework for meaningful communication. But what do people fill that framework up with? The answer is, of course, words. Every human language has a lexicon—the sum total of all of the words in that language. By using grammatical rules to combine words into logical sentences, humans can convey an infinite number of concepts.

3) Introduction to Linguistics
Language is such a special topic that there is an entire field, linguistics, devoted to its study. Linguistics views language in an objective way, using the scientific method and rigorous research to form theories about how humans acquire, use, and sometimes abuse language. There are a few major branches of linguistics, which it is useful to understand in order to learn about language from a psychological perspective.
Major levels of linguistics: These are the various subfields of linguistics, the study of language. These include phonetics, phonology, morphology, syntax, semantics, and pragmatics.

4) Phonetics and Phonology
Phonetics is the study of individual speech sounds; phonology is the study of phonemes, which are the speech sounds of an individual language. These two heavily overlapping subfields cover all the sounds that humans can make, as well as which sounds make up different languages. A phonologist could answer the question, “Why do BAT and TAB have different meanings even though they are made of the
same three sounds, A, B, and T?”

5) Morphology
Morphology is the study of words and other meaningful units of languages like suffixes and prefixes. A morphologist would be interested in the relationship between words like “dog” and “dogs” or “walk” and “walking,” and how people figure out the differences between those words.

6) Semantics and Pragmatics
Semantics, most generally, is about the meaning of sentences. Someone who studies semantics is interested in words and what real-world object or concept those words denote, or point to. Pragmatics is an even broader field that studies how the context of a sentence contributes to meaning—for example, someone shouting “Fire!” has a very different meaning if they are in charge of a seven-gun salute than it does if they are sitting in a crowded movie theater.

All languages have underlying structural rules that make meaningful communication possible.
Every language is different. In English, an adjective comes before a noun (“red house”), whereas in Spanish, the adjective comes after (“casa [house] Roja [red].”) In German, you can put noun after noun together to form giant compound words; in Chinese, the pitch of your voice determines the meaning of your words; in American Sign Language, you can convey full, grammatical sentences with tense and aspect by moving your hands and face. But all languages have structural underpinnings that make them logical for the people who speak and understand them.
Five major components of the structure of language are phonemes, morphemes, lexemes, syntax, and context. These pieces all work together to create meaningful communication among individuals.
