Chapter 4 MorphologyWhat is morphology?The total number of words stored in the brain is called the lexicon.Words are the smallest free units of language that unite sounds with meaning. Morphology is defined as the study of the internal structure and the formation of words.Morphemes and allomorphsThe smallest meaningful unit of language is called a morpheme.A morpheme may be represented by different forms, called allomorphs.“zero” form of a morpheme and suppletivesSome countable nouns do not change form to express plurality. Similarly, some regular verbs do not change form to indicate past tense. In these two cases, the noun or verb contains two morphemes, among which there is one “zero form” of a morpheme.Some verbs have irregular changes when they are in past tense. In this case, the verbs also have two morphemes. Words which are not related in form to indicate grammatical contrast with their roots are called suppletives.Free and bound morphemesSome morphemes constitute words by themselves. These morphemes are called free morphemes.Other morphemes are never used independently in speech and writing. They are always attached to free morphemes to form new words. These morphemes are called bound morphemes.The distinction between a free morphemes and a bound morpheme is whether it can be used independently in speech or writing.Free morphemes are the roots of words, while bound morphemes are the affixes (prefixes and suffixes).Inflexional and derivational morphemesInflexional morphemes in modern English indicate case and number of nouns, tense and aspect of verbs, and degree of adjectives and adverbs.Derivational morphemes are bound morphemes added to existing forms to construct new words.English affixes are divided into prefixes and suffixes.Some languages have infixes, bound morphemes which are inserted into other morphemes.The process of putting affixes to existing forms to create new words is called derivation. Words thus formed are called derivatives.Conclusion: classification of morphemesMorphemesFree morphemesBound morphemesInflexionalDerivational: affixesPrefixes: -s, -’s, -er, -est, -ing, -ed, -sSuffixesFormation of new wordsDerivationDerivation forms a word by adding an affix to a free morpheme.Since derivation can apply more than once, it is possible to create a derived word with a number of affixes. For example, if we add affixes to the word friend, we can form befriend, friendly, unfriendly, friendliness, unfriendliness, etc. This process of adding more than one affix to a free morpheme is termed complex derivation. Derivation does not apply freely to any word of a given category. Generally speaking, affixes cannot be added to morphemes of a different language origin. Derivation is also constrained by phonological factors.Some English suffixes also change the word stress.CompoundingCompounding is another common way to form words. It is the combination of free morphemes.The majority of English compounds are the combination of words from the three classes – nouns, verbs and adjectives – and fall into the three classes.In compounds, the rightmost morpheme determines the part of speech of the word. The meaning of compounds is not always the sum of meaning of the components. ConversionConversion is the process putting an existing word of one class into another class. Conversion is usually found in words containing one morpheme.ClippingClipping is a process that shortens a polysyllabic word by deleting one or more syllables.Clipped words are initially used in spoken English on informal occasions.Some clipped words have become widely accepted, and are used even in formal styles. For example, the words bus (omnibus), vet (veterinarian), gym (gymnasium), fridge (refrigerator) and fax (facsimile) are rarely used in their complete form.BlendingBlending is a process that creates new words by putting together non-morphemic parts of existing words. For example, smog (smoke + frog), brunch (a meal in the middle of morning, replacing both breakfast and lunch), motel (motor + hotel). Thereis also an interesting word in the textbook for junior middle school students –“plike” (a kind of machine that is like both a plane and a bi ke).Back-formationBack-formation is the process that creates a new word by dropping a real or supposed suffix. For example, the word televise is back-formed from television. Originally, the word television is formed by putting the prefix tele- (far) to the root vision (viewing). At the same time, there is a suffix –sion in English indicating nouns. Then people consider the –sion in the word television as that suffix and drop it to form the verb televise.Acronyms and abbreviationsAcronyms and abbreviations are formed by putting together the initial letters of all words in a phrase or title.Acronyms can be read as a word and are usually longer than abbreviations, which are read letter by letter.This type of word formation is common in names of organizations and scientific terminology.EponymsEponyms are words that originate from proper names of individuals or places. For example, the word sandwich is a common noun originating from the fourth Earl of Sandwich, who put his food between two slices of bread so that he could eat while gambling.CoinageCoinage is a process of inventing words not based on existing morphemes.This way of word formation is especially common in cases where industry requires a word for a new product. For example, Kodak and Coca-cola.For more detailed explanation to the ways of word formation, see my notes of Practical English Grammar.转自[英美者]-英语专业：.enmajor./cn/Html/M/Linguistics/86983.htmlChapter 3 PhonologyWhat is phonology?Phonology is the study of sound systems and patterns.Phonology and phonetics are two studies different in perspectives, which are concerned with the study of speech sounds.Phonology focuses on three fundamental questions.What sounds make up the list of sounds that can distinguish meaning in a particular language?What sounds vary in what ways in what context?What sounds can appear together in a sequence in a particular language?Phonemes and allophonesA phoneme is a distinctive, abstract sound unit with a distinctive feature.The variants of a phoneme are termed allophones.We use allophones to realize phonemes.Discovering phonemesContrastive distribution – phonemesIf sounds appear in the same environment, they are said to be in contrastive distribution.Typical contrastive distribution of sounds is found in minimal pairs and minimal sets.A minimal pair consists of two words that differ by only one sound in the same position.Minimal sets are more than two words that are distinguished by one segment in the same position.The overwhelming majority of the consonants and vowels represented by the English phonetic alphabet are in contrastive distribution.Some sounds can hardly be found in contrastive distribution in English. However, these sounds are distinctive in terms of phonetic features. Therefore, they are separate phonemes.Complementary distribution – allophonesSounds that are not found in the same position are said to be in complementary distribution.If segments are in complementary distribution and share a number of features, they are allophones of the same phoneme.Free variationIf segments appear in the same position but the mutual substitution does not result in change of meaning, they are said to be in free variation.Distinctive and non-distinctive featuresFeatures that distinguish meaning are called distinctive features, and features do not, non-distinctive features.Distinctive features in one language may be non-distinctive in another.Phonological rulesPhonemes are abstract sound units stored in the mind, while allophones are the actual pronunciations in speech.What phoneme is realized by what allophones in what specific context is another major question in phonology.The regularities that what sounds vary in what ways in what context are generalized and stated in phonology as rules.There are many phonological rules in English. Take the following ones as examples. [+voiced +consonant] – [-voiced]/[-voiced +consonant]_[-voiced +bilabial +stop] – unaspirated/[-voiced +alveolar +fricative]_Syllable structureA syllable is a phonological unit that is composed of one or more phonemes. Every syllable has a nucleus, which is usually a vowel.The nucleus may be preceded by one or more consonants called the onset and followed by one or more consonants called the coda.Sequence of phonemesNative speakers of any language intuitively know what sounds can be put together.Some sequences are not possible in English. The impossible sequences are called systematic gaps.Sequences that are possible but do not occur yet are called accidental gaps.When new words are coined, they may fill some accidental gaps but they will never fill systematic gaps.Suprasegmental featuresFeatures that are found over a segment or a sequence of two or more segments are called suprasegmental features.These features are distinctive features.StressStress is the perceived prominence of one or more syllabic elements over others in a word.Stress is a relative notion. Only words that are composed of two or more syllables have stress.If a word has three or more syllables, there is a primary stress and a secondary stress.In some languages word stress is fixed, i.e. on a certain syllable. In English, word stress is unpredictable.IntonationWhen we speak, we change the pitch of our voice to express ideas.Intonation is the variation of pitch to distinguish utterance meaning.The same sentence uttered with different intonation may express different attitude of the speaker.In English, there are three basic intonation patterns: fall, rise, fall-rise. ToneTone is the variation of pitch to distinguish words.The same sequence of segments can be different words if uttered with different tones.Chinese is a typical tone language.-转自[英美者]-英语专业：.enmajor./cn/Html/M/Linguistics/86123.htmlChapter 2 PhoneticsWhat is phonetics?Phonetics is termed as the study of speech sounds.Sub-branches of phoneticsArticulatory phonetics – the production of speech soundsAcoustic phonetics – the physical properties of speech soundsAuditory phonetics – the perceptive mechanism of speech soundsThe speech organsWhere does the air stream come from?From the lungWhat is the function of vocal cords?Controlling the air streamWhat are the cavities?Oral cavityPharyngeal cavityNasal cavityTranscription of speech soundsUnits of representationSegments (the individual sounds)Phonetic symbolsThe widely used symbols for phonetic transcription of speech sounds is the International Phonetic Alphabet (IPA).The IPA attempts to represent each sound of human speech with a single symbol and the symbols are enclosed in brackets [ ] to distinguish phonetic transcriptions from the spelling system of a language.In more detailed transcription (narrow transcription) a sound may be transcribed with a symbol to which a smaller is added in order to mark the finer distinctions.Description of speech soundsDescription of English consonantsGeneral feature: obstructionCriteria of consonant descriptionPlaces of articulationManners of articulationVoicing of articulationPlaces of articulationThis refers to each point at which the air stream can be modified to produce a sound.Bilabial: [p] [b] [m] [w]Labiodental: [f] [v]Interdental: [] []Alveolar: [t] [d] [s] [z] [l] [n] [r]Palatal: [] [] [t] [d] [j]Velar: [k] [g] []Glottal: [h]Manners of articulationThis refers to how the air stream is modified, whether it is completely blocked or partially obstructed.Stops: [p] [b] [t] [d] [k] [g]Fricatives: [s] [z] [] [] [f] [v] [] [] [h]Affricates: [t] [d]Liquids: [l] [r]Glides: [w] [j]Nasals: [m] [n] []Voicing of articulationThis refers to the vibrating of the vocal cords when sounds are produced.Voiced soundsVoiceless soundsDescription of English vowelsGeneral feature: without obstructionCriteria of vowel descriptionPart of the tongue that is raisedFrontCentralBackExtent to which the tongue rises in the direction of the palateHighMidLowKind of opening made at the lipsPosition of the soft palateSingle vowels (monophthongs) and diphthongsPhonetic features and natural classesClasses of sounds that share a feature or features are called natural classes.
