I. Morphology • Morph (form) + ology (science of) • -- > Morphology (the science of word forms) • The study of the internal structure of words • The rules by which words are formed
Traditionally, the term “morphology” refers to the study of “morphemes”. • But…what’s a morpheme?
I. 1. What is morpheme? • Dictionary: • Morpheme • (môr'fēm') • n. • A meaningful linguistic unit consisting of a word, such as man, or a word element, such as -ed in walked, that cannot be divided into smaller meaningful parts. • morphemic mor·phem'icadj. • morphemically mor·phem'i·cal·lyadv. http://www.answers.com/topic/morpheme
EX: speak (v.) + -er = speaker (n.) • The “-er” that changes “speak” to “speaker” is a part of what’s known as the derivational morphology of English. • Derivational morphology deals with morphemes that change the lexical category of the word they are added to. • Since “-er” changes “speak”, a verb, to “speaker”, a noun, we can say it derives the noun “speaker” from the verb “speak”. • A morpheme is a piece of phonological information that has a conventionalized meaning arbitrarily associated with it.
I.1.1.Derivational morphemes • Far more numerous than inflectional morphemes • Allow productivity (involved in the coining of new words) • Can be prefixes, or suffixes • Suffixes usually, but not always, change word class • Prefixes, usually don’t
Derivational morphemes derive one word from another. • They have the following properties: • - They affect the meaning of the morpheme that they attach to. • E.g. re- means to redo the process, de- means to undo the process, un- means not…. • - They can change the grammatical category of the word they attach to. • E.g. noun becomes adjective, adjective becomes verb, etc. • - They can be used to create new words, such as debug, reboot, unbirthday, etc.
Prefix: An affix that occurs before a morpheme It changes the type of meaning of the word. Suffix: An affix that occurs after a morpheme It changes the category and/or the type of meaning of the word, so it is said to create a new word. e.g. suffix –ment in government English Affixes(based on the position)
English Prefixes Examples of Negative Prefixes: un- non- dis- a- Examples of size and degree prefixes: mini- sub- over- super-
Class preserving suffixation: -er lecturer -ian librarian -ist scientist -let piglet Class changing suffixation: Verb Noun perform performance Adjective Adverb nice nicely Adjective Noun active activity English Suffixes
Some examples of English Derivational Morpheme • -ic : Noun Adj ; alcohol alcoholic • -ance : Verb Noun ; clear clearance • -ly : Adj Adv ; exact exactly • -ity : Adj Noun ; active activity • -able : Verb Adj ; read readable • -ship : Noun Noun ; friend friendship • re- : Verb Verb ; cover recover • in- : Adj Adj ; definite indefinite
Add the prefix un to each word. ACTIVITY 1. The prefix un means the opposite. happy Un + happy = Un + lock = lock zip Un + zip = Sixth grade
ACTIVITY 2. Add the prefix dis to each word The prefix dis means the opposite. like dis + like = ……………………………………………. agree dis + agree =………………………………………. dis + connect = ……………………………. connect
