In linguistics, an affix is a morpheme that is attached to a word stem to form a new word or word form. The main two categories are derivational and inflectional affixes. Derivational affixes, such as un-, -ation, anti-, pre- etc., introduce a semantic change to the word they are attached to. Inflectional affixes introduce a syntactic change, such as singular into plural, or present simple tense into present continuous or past tense by adding -ing, -ed to an English word. All of them are bound morphemes by definition; prefixes and suffixes may be separable affixes.
A lexicon is the vocabulary of a language or branch of knowledge. In linguistics, a lexicon is a language's inventory of lexemes. The word lexicon derives from Greek word λεξικόν, neuter of λεξικός meaning 'of or for words'.
In linguistics, morphology is the study of words, including the principles by which they are formed, and how they relate to one another within a language. Most approaches to morphology investigate the structure of words in terms of morphemes, which are the smallest units in a language with some independent meaning. Morphemes include roots that can exist as words by themselves, but also categories such as affixes that can only appear as part of a larger word. For example, in English the root catch and the suffix -ing are both morphemes; catch may appear as its own word, or it may be combined with -ing to form the new word catching. Morphology also analyzes how words behave as parts of speech, and how they may be inflected to express grammatical categories including number, tense, and aspect. Concepts such as productivity are concerned with how speakers create words in specific contexts, which evolves over the history of a language.
In historical linguistics, a sound change is a change in the pronunciation of a language. A sound change can involve the replacement of one speech sound by a different one or a more general change to the speech sounds that exist, such as the merger of two sounds or the creation of a new sound. A sound change can eliminate the affected sound, or a new sound can be added. Sound changes can be environmentally conditioned if the change occurs in only some sound environments, and not others.
The apostrophe is a punctuation mark, and sometimes a diacritical mark, in languages that use the Latin alphabet and some other alphabets. In English, the apostrophe is used for three basic purposes:
In linguistics, an elision or deletion is the omission of one or more sounds in a word or phrase. However, these terms are also used to refer more narrowly to cases where two words are run together by the omission of a final sound. An example is the elision of word-final /t/ in English if it is preceded and followed by a consonant: "first light" is often pronounced "firs' light". Many other terms are used to refer to specific cases where sounds are omitted.
Sandhi is any of a wide variety of sound changes that occur at morpheme or word boundaries. Examples include fusion of sounds across word boundaries and the alteration of one sound depending on nearby sounds or the grammatical function of the adjacent words. Sandhi belongs to morphophonology.
In phonology, syncope is the loss of one or more sounds from the interior of a word, especially the loss of an unstressed vowel. It is found in both synchronic and diachronic analyses of languages. Its opposite, whereby sounds are added, is epenthesis.
A contraction is a shortened version of the spoken and written forms of a word, syllable, or word group, created by omission of internal letters and sounds.
A word is a basic element of language that carries meaning, can be used on its own, and is uninterruptible. Despite the fact that language speakers often have an intuitive grasp of what a word is, there is no consensus among linguists on its definition and numerous attempts to find specific criteria of the concept remain controversial. Different standards have been proposed, depending on the theoretical background and descriptive context; these do not converge on a single definition. Some specific definitions of the term "word" are employed to convey its different meanings at different levels of description, for example based on phonological, grammatical or orthographic basis. Others suggest that the concept is simply a convention used in everyday situations.
In phonology, hiatus or diaeresis describes the occurrence of two separate vowel sounds in adjacent syllables with no intervening consonant. When two vowel sounds instead occur together as part of a single syllable, the result is called a diphthong.
In phonology, apocope is the loss (elision) of a word-final vowel. In a broader sense, the term can refer to the loss of any final sound from a word.
Neoclassical compounds are compound words composed from combining forms derived from classical languages roots. Neo-Latin comprises many such words and is a substantial component of the technical and scientific lexicon of English and other languages, via international scientific vocabulary (ISV). For example, Greek bio- combines with -graphy to form biography.
A synalepha or synaloepha is the merging of two syllables into one, especially when it causes two words to be pronounced as one.
In linguistics, synaeresis is a phonological process of sound change in which two adjacent vowels within a word are combined into a single syllable.
In linguistics, a blend—also known as a blend word, lexical blend, or portmanteau—is a word formed by combining the meanings, and parts of the sounds, of two or more words together. English examples include smog, coined by blending smoke and fog, as well as motel, from motor (motorist) and hotel.
English prefixes are affixes that are added before either simple roots or complex bases consisting of (a) a root and other affixes, (b) multiple roots, or (c) multiple roots and other affixes. Examples of these follow:

An agglutinative language is a type of synthetic language with morphology that primarily uses agglutination. In an agglutinative language, words contain multiple morphemes concatenated together, but in such a manner that individual word stems and affixes can be isolated and identified as to indicate a particular inflection or derivation, although this is not a rule: for example, Finnish is a typical agglutinative language, but morphemes are subject to consonant alternations called consonant gradation.
In linguistics, a clipped compound is a word produced from a compound word by reducing its parts while retaining the meaning of the original compound. It is a special case of word formation called clipping.
