Let us begin   :   Lesson (1)
Chapter ( 5 )        The Meaning of Language

How to learn language ?
Knowing a language is knowing how to produce and understand sentenses with particular meanings . To understand language we need to know the meaning of words and the morphemes* that compose them . We also must know how the meanings of words combine into phrase and sentence meanings . Finally , we must interpret the meaning of utterances in the context in which they are made.

What is a morpheme ?
A morpheme is the smallest unit of linguistic meaning that is indivisible , i.e
the word " desire " includes only one morpheme , we can't divide it into parts .
While the word " desirable ' includes two morphemes ( desire ) and ( able )

( -ish , -ly , -dis , -un , -ness ,  .......... etc ) are called bound morphemes , they include suffixes and prefixes and they can't occur alone, they must be attached to other morphemes to constitute words ; we can't say ( ly ) but we can say ( friendly )

Some Definitions
Semantics : It is the study of the linguistic meaning of morphemes , words , phrases , and sentences .
Lexical Semantics : It is subfield of semantics which is concerned with the meanings of words .
Phrasal Semantics : It is concerned with the meaning of syntactic units larger than the word.
Pragmatics : It is the study of how context affects meaning . E.g : How the sentense " it's cold here " comes to be interpreted as " close the window " in certain situations.

Semantic Properties are information on which speaker of the language agree .
Words can be either content or function .  Words like adjectives , verbs , adverbs are called content words.
Function Words : connect the content words together such as prepositions , conjunctions , ....... etc.[/englishtext]
