    1. Assessment of Morphology & Syntax Expression

    2. Objectives What is MLU Stages of Syntactic Development Examples of Difficulties in Syntax Why preferring the term �morphosyntax� The Assessment Methods of Analysis

    3. What is MLU? stands for mean length of utterance a measure of syntax development is the average number of morphemes or words that a client produces in an utterance N.B. MLU for words does not reflect the use of bound morphemes (i.e. will be equal to or smaller than the MLU for morphemes)

    4. MLU (Cont�d) provides important information about language development i.e. an indicator of a language delay or disorder For Computing MLU, look at : Box 6-3 Page 205-206 (Lund & Duchan)

    5. Syntactic Development One word syntax Word acts like a whole sentence Holophrase? single words express ideas adults would say in a sentence Contains pragmatic & semantic information

    6. One word syntax (Cont�d) Transition to syntax end of the of the single-word period Using the same word with different intonation patterns or with accompanying gestures to express different intentions The use of successive single words that relate to the same event Indications of moving toward word combinations

    7. Two word combinations 18-20 months When have acquired about 50 single words Telegraphic utterances They contain Content-carrying words (nouns,verbs ,& adjectives) Low-information words (pronouns,articles,prepositions ) + inflectional morphemes

    8. Multiword combinations Utterances of 3 or more words When equal numbers of 1-word & 2-word utterances are produced MLU (1.5) Simple clauses Simple clauses that appear at this stage more expanded (articles, adj., adv., � are added) combined to form multiclause utterances

    9. Multiword combinations (Cont�d) Development of verbs Simple action verbs (e.g. eat & do) Verbs indicating change in location (e.g. put & sit) Verbs indicating the state of the subject (e.g. want & know) Demonstrative pronouns (e.g. this, that & it) appear frequently as the subject of the sentence e.g. That a cow

    10. Multiple clauses Appear between 2-3 years of age MLU (3+) Appearance of multiple clauses with no connectives (e.g. you take that one, I take that one) Appearance of connective and Connecting words Connecting 2 clauses
