هذا القسم يحتوي علي كل ما يخص بعلم الصرف

يتوفر علم الصرف على تبيان تأليف الكلمة المفردة بتبيان وزنها وعدد حروفها و حركاتها و ترتيبها، و ما يعرض لذلك من تغيير وحذف، وما في حروفها و حركاتها و ترتيبهما، وما في حروف الكلمة من اصالة و زيادة.

يقتصر مجال دراسات الصرف على الأسماء المتمكنة (المعربة) و الافعال المتصرفة (غير جامدة).

أما الحروف و مبنيات الأسماء و جوامد الافعال، فلا تدخل في مجال دراسته و أبحاثه.

يُعرَفُ الصرف أيضا بعلم التشكل (باللاتينية: Morphologia). والصرف لُغَةً هو التغير والتحويل ومنه تصريف الرياح أي تغيير وجهتها من مكان لآخر.

In linguistics, morphology (/mɔːrˈfɒlədʒi/) is the study of words, how they are formed, and their relationship to other words in the same language. It analyzes the structure of words and parts of words, such as stems, root words, prefixes, and suffixes. Morphology also looks at parts of speech, intonation and stress, and the ways context can change a word's pronunciation and meaning. Morphology differs from morphological typology, which is the classification of languages based on their use of words, and lexicology, which is the study of words and how they make up a language's vocabulary.]

While words, along with clitics, are generally accepted as being the smallest units of syntax, in most languages, if not all, many words can be related to other words by rules that collectively describe the grammar for that language. For example, English speakers recognize that the words dog and dogs are closely related, differentiated only by the plurality morpheme "-s", only found bound to noun phrases. Speakers of English, a fusional language, recognize these relations from their innate knowledge of English's rules of word formation. They infer intuitively that dog is to dogs as cat is to cats; and, in similar fashion, dog is to dog catcher as dish is to dishwasher. By contrast, Classical Chinese has very little morphology, using almost exclusively unbound morphemes ("free" morphemes) and depending on word order to convey meaning. (Most words in modern Standard Chinese ["Mandarin"], however, are compounds and most roots are bound.) These are understood as grammars that represent the morphology of the language. The rules understood by a speaker reflect specific patterns or regularities in the way words are formed from smaller units in the language they are using, and how those smaller units interact in speech. In this way, morphology is the branch of linguistics that studies patterns of word formation within and across languages and attempts to formulate rules that model the knowledge of the speakers of those languages.

Phonological and orthographic modifications between a base word and its origin may be partial to literacy skills. Studies have indicated that the presence of modification in phonology and orthography makes morphologically complex words harder to understand and that the absence of modification between a base word and its origin makes morphologically complex words easier to understand. Morphologically complex words are easier to comprehend when they include a base word.[6]

Polysynthetic languages, such as Chukchi, have words composed of many morphemes. The Chukchi word "təmeyŋəlevtpəγtərkən", for example, meaning "I have a fierce headache", is composed of eight morphemes t-ə-meyŋ-ə-levt-pəγt-ə-rkən that may be glossed. The morphology of such languages allows for each consonant and vowel to be understood as morphemes, while the grammar of the language indicates the usage and understanding of each morpheme.

The discipline that deals specifically with the sound changes occurring within morphemes is morphophonology.

What is Morphology?
Morphology is the study of form and structure.
In linguistics, it generally refers to the study of form and
structure of words.

Introduction
What are morphemes?
What is morphology?
The term Morphology can refer to three different things
a Description of the behaviour of morphemes and how they
are combined.
b Derivational, inflectional and compositional processes of
word formation occurring in a specific language.
e.g. “German has a richer morphology than English”
c Description of such word formation processes.
