Syntax: Structure of sentences. Morphology: Structure of words words.. Phonology: Structure of sounds. Phonetics: How sounds are articulated. Basics Syntax • • Syntax is the study of the structure of sentences. • • • Phonemes combine to form morphemes. Morphemes combine to form words. Words combine to form sentences. Not so simple… A sentence expresses a complete meaning. • • A phoneme has no meaning. A morpheme is the smallest unit that expresses a meaning. From Phonemes to Sentences • • • Languages usually have around 25 different phonemes. • • Around 10,000-50,000 different morphemes. How many different sentences? • Unlimited. The meaning of every morpheme must be memorized. • If you’ve never heard the morpheme wug before, you can’t figure it out. The meaning of every sentence is predictable given the parts. • If you’ve never heard the sentence My hovercraft is full of eels before, you can still understand it. Compositionality • Sentences follow the principle of compositionality: the meaning of the whole is the meaning of the parts plus how they are combined. form “the cat sat on the mat” meaning Compositionality • Sentences follow the principle of compositionality: the meaning of the whole is the meaning of the parts plus how they are combined. • • • So, what are the parts? • Syntactic categories. And what are the ways that they are combined? • Syntactic rules. Of all the possible combinations of words, only a few form meaningful sentences. Grammar • In syntax, we categorize sequences of words as grammatical or ungrammatical within a language. • A mental grammar is a speaker’s unconscious knowledge of how a language works. • When you know a language, you know its rules: Phonological rules, morphological processes, syntactic rules, … /t/ z +/ - /æ _V ‘ / ] ʰ t +/ >[ /- d/ l ra m or /t of plu > to [æ ̃] fo rm /_ N pa st SYNTACTIC RULES te ns e Grammar • A sentence is grammatical in a language if it follows the rules in the mental grammar of that language. • A sentence is ungrammatical if it breaks those rules: that is, if it is something that people would not say. My hovercraft is full of eels. ✓ * Hovercraft of full eels my is. ✗ Prescriptive vs. Descriptive Grammar • When you learned “grammar” in school, you may have learned things like: • “Don’t end a sentence with a preposition” • • • • “Don’t use passive voice” “Don’t use less with a count noun, like less customers. You should say fewer customers.” This is prescriptive grammar: Someone’s ideas about what makes for “correct” or good writing. • Not our business as scientists! We’re interested in descriptive grammar: a description of the rules people actually do follow in normal language use. Grammaticality • A sentence is grammatical in a language if it follows the rules in the mental grammar of that language. • A sentence is ungrammatical if it breaks those rules: that is, if it is something that people would not say. • In studying syntax we will rely on grammaticality judgments: a speaker’s intuitive judgment about whether a sentence is grammatical or not. • If a sentence is grammatical we also call it well-formed. Syntax and Meaning • • Grammaticality is separate from plausibility! It doesn’t matter how nonsensical or false the meaning is, all that matters is that it follows the rules of the language. Colorless green ideas sleep furiously. ✓ Syntax and Meaning • • Grammaticality is separate from plausibility! It doesn’t matter how nonsensical or false the meaning is, all that matters is that it follows the rules of the language. ✓ Green sleep colorless furiously ideas. ✗ * Colorless green ideas sleep furiously. Syntax and Meaning • • Grammaticality is separate from plausibility! It doesn’t matter how nonsensical or false the meaning is, all that matters is that it follows the rules of the language. I have a friend who is always full of ideas, good ideas and bad ideas, fine ideas and crude ideas, old ideas and new ideas. Before putting his new ideas into practice, he usually sleeps over them to let them mature and ripen. However, when he is in a hurry, he sometimes puts his ideas into practice before they are quite ripe, in other words, while they are still green. Some of his green ideas are quite lively and colorful, but not always, some being quite plain and colorless. When he remembers that some of his colorless ideas are still too green to use, he will sleep over them, or let them sleep, as he puts it. But some of those ideas may be mutually conflicting and contradictory, and when they sleep together in the same night they get into furious fights and turn the sleep into a nightmare. Thus my friend often complains that his colorless green ideas sleep furiously. Syntax and Meaning • • Grammaticality is separate from plausibility! • A sentence is grammatical when it is something someone would say, no matter how unlikely the context! It doesn’t matter how nonsensical or false the meaning is, all that matters is that it follows the rules of the language. Grammaticality I bought a dog. ✓ * Me bought a dog. ✗ Grammaticality Sally ate an apple. Sally ate a tree. * Sally a tree ate. * Sally ate an exploded. ✓ ✓ ✗ ✗ Grammaticality Sally likes Bob. Bob likes Sally. * Likes Sally Bob. ✓ ✓ ✗ Grammaticality Sally will go to a store. * Sally has go to a store. Sally has gone to a store. * Store a Sally gone to has. ✓ ✗ ✓ ✗ Grammaticality France is in Europe. * France are in Europe. France is in Africa. ✓ ✗ ✓ Grammaticality This dog is mine. * This dog is my. This is my dog. * This is mine dog. ✓ ✗ ✓ ✗ Grammaticality ✓ Sally ate. ✓ Sally put the cup on the table. ✓ Sally put. ✗ * Sally ate the food. Syntactic Categories Syntactic Category • How do we describe what makes some sequences of words grammatical, and others ungrammatical? • The fundamental unit in syntax is the syntactic category. • Preliminary definition: Two words are in the same syntactic category iff you can interchange them in every sentence without making the sentence ungrammatical. • Alternatively: Two words are in different syntactic categories iff you can find a sentence where interchanging them makes a grammatical sentence ungrammatical. Syntactic Category • Example: Are cat and explode in the same syntactic category? • • • 1. Find a grammatical sentence containing cat. • I saw the cat. ✓ 2. Try substituting explode instead of cat. • * I saw the explode. ✗ 3. Therefore, cat and explode are in different syntactic categories. ➡cat is a noun (N), explode is a verb (V). Syntactic Category • Example: Are cat and mouse in the same syntactic category? • • • • 1. Find a grammatical sentence containing cat. • I saw the cat. ✓ 2. Try substituting mouse instead of cat. • I saw the mouse. ✓ 3. Are there any examples where it doesn’t work? 4. If no examples, then they are in the same syntactic category. ➡Both nouns (N). Syntactic Category • Example: Are Mary and mouse in the same syntactic category? • • • 1. Find a grammatical sentence containing Mary. • Mary is my friend. ✓ 2. Try substituting mouse instead of Mary. • * Mouse is my friend. ✗ 3. The substitution made the sentence ungrammatical, so they are in different syntactic categories. Syntactic Category • Example: Are the and my in the same syntactic category? • • • • 1. Find a grammatical sentence containing the. • Hand me the salt. ✓ 2. Try substituting my instead of the. • Hand me my salt. ✓ 3. Repeat the process. Are there any examples where it doesn’t work? 4. None, so they are in the same category. ➡ Both determiners (Det). Syntactic Category • Example: Are the and blue in the same syntactic category? • • 1. Find a grammatical sentence containing the. • I like the salt. ✓ 2. Try substituting blue instead of the. • I like blue salt. ✓ • 3. Repeat the process. Are there any examples where it doesn’t work? • How about the other way? • • • The blanket is blue. * The blanket is the. ✓ ✗ 4. The substitution made the sentence ungrammatical, so they are in different categories. • • Blue is an adjective. (Adj) The is a determiner. (Det) Syntactic Category: Not Just Words • • Syntactic categories cover more than just words! • Example: Are the cat and a dog in the same syntactic category? For any two sequences of words, if you can interchange them in all sentences without making the sentence ungrammatical, then they are in the same syntactic category. • • Start sentence: I think the cat is cute. ‣ I think a dog is cute. ✓ ✓ For any sentence you can think of that contains the cat, you can substitute a dog and it’s still grammatical. Syntactic Category • A syntactic category consisting of a sequence of words is called a phrase. • • The cat and a dog are in the same category: both are noun phrases (NP) Better definition: Two words or phrases are in the same syntactic category iff you can interchange them in every sentence without making the sentence ungrammatical. Syntactic Category • Example: Are dog and the cat in the same syntactic category? • • • 1. Find a grammatical sentence containing dog. • I have a dog. ✓ 2. Try substituting the cat instead of dog. • * I have a the cat. ✗ 3. The substitution makes the sentence ungrammatical, so they are not in the same syntactic category. ➡ Dog is a noun (N). ➡ The cat is a noun phrase (NP). Some Common Syntactic Categories • • • • • • • Nouns (N): cat, dog, car, water, salt, … • Verb phrases (VP): Anything that you can substitute with did so, do so, or does so. • Prepositional phrases (PP): Phrases like in the park Verbs (V): goes, went, runs, ran, … Adjectives (Adj): big, red, beautiful, angry, … Adverbs (Adv): quickly, fast, well, unfortunately, … Determiners (Det): a(n), the, this, that, those, my, your, … Prepositions (P): in, of, at, from, by, … Noun phrases (NP): Anything that can you can substitute with a pronoun (he, she, it, him, her, they, them). What is a sentence? • A sentence is a phrase that can appear in this context: • Sally thinks that ___________________. ‣ Sally thinks that the cat is cute. ➡the cat is cute is a sentence. ‣ *Sally thinks that the cat. ➡The cat is not a sentence. Syntactic Constraints Syntactic Constraints • The goal of syntax is to figure out what are the rules that make some combinations of words grammatical, and others ungrammatical? • Two kinds of constraints on words in sentences: • • Co-occurrence constraints • If you have one word somewhere in a sentence, you must also have another word somewhere else in the sentence. Word order constraints: • Words must be placed in a certain order for a sentence to be grammatical. Co-Occurrence Constraints Sally hasn’t read the book. * Sally hasn’t read the this book. * Sally hasn’t read three book. * Sally hasn’t read the. Sally hasn’t read three books. ✓ ✗ ✗ ✗ ✓ Co-Occurrence Constraints • • • Sometimes a word requires the presence of another word. • Sally hasn’t read the book. • *Sally hasn’t read the. ➡A determiner (Det) requires a noun (N). Sometimes a word rules out the presence of another word. • *Sally hasn’t read the this book. ➡A determiner (Det) rules out other determiners (Det). Sometimes a word requires that another word be in a certain morphological form. • *Sally hasn’t read three book. • Sally hasn’t read three books. ➡A number word (Num) requires a plural noun (plural N). Word Order Constraints Sally hasn’t read the book. * Sally hasn’t read book the. Sally saw the book. * * Saw Sally the book. Sally the book saw. ✓ ✗ ✓ ✗ ✗ Word Order Constraints • Certain words are required to go before other words. • Sally read the book. • *Sally read book the. ➡“the” must go before a noun. (Det N) • Sally saw the book. • *Saw Sally the book. ➡ The subject of a verb must go before the verb (V). • Certain words are required to go after other words. • Sally saw the book. • *Sally the book saw. ➡ The object of a verb must go after the verb (V). • English has the order Subject—Verb—Object. Introduction to Linguistics Syntax II Syntax So Far • • Syntax is the study of the structure of sentences. A sentence is grammatical in a language if it follows the rules that you know implicitly as a speaker of that language. • • We’ve seen phonological and morphological rules. What do syntactic rules look lile? Words and sequences of words fall into syntactic categories: if two words or sequences of words can be substituted for each other in all sentences, then they are in the same syntactic category. Syntactic Category • Example: Are cat and mouse in the same syntactic category? • • • • 1. Find a grammatical sentence containing cat. • I saw the cat. ✓ 2. Try substituting mouse instead of cat. • I saw the mouse. ✓ 3. Are there any examples where it doesn’t work? 4. If no examples, then they are in the same syntactic category. ➡Both nouns (N). Syntactic Category • Example: Are the and blue in the same syntactic category? • • • 1. Find a grammatical sentence containing the or blue. • The blanket is blue. 2. See what happen when you substitute the for blue. • * The blanket is the. 4. The substitution made the sentence ungrammatical, so they are in different categories. • • Blue is an adjective. (Adj) The is a determiner. (Det) Syntactic Category • Example: Are cat and the cat in the same syntactic category? • • • 1. Find a grammatical sentence containing cat or the cat. • I like the cat. 2. See what happen when you substitute the cat for cat. • * I like the the cat. 3. Therefore they are in different categories. • cat is a noun (N) • The cat is a noun phrase (NP) NP Det N the cat Syntactic Category • Example: Are cat and furry cat in the same syntactic category? • • • 1. Find a grammatical sentence containing cat or furry cat. • I like the furry cat. 2. See what happen when you substitute cat for furry cat. • I like the cat. 3. Are there any examples where it becomes ungrammatical? N Adj N furry cat Syntactic Category • Example: Are the furry cat and furry cat in the same syntactic category? • • • 1. Find a grammatical sentence containing the furry cat or furry cat. • I like the furry cat. 2. See what happen when you substitute the furry cat for furry cat. • *I like the the furry cat. 3. They are in different categories • • NP Noun (N) vs. Noun Phrase (NP) N Det Adj N I like the furry cat Syntactic Constraints Syntactic Constraints • The goal of syntax is to figure out what are the rules that make some combinations of words grammatical, and others ungrammatical? • Two kinds of constraints on words in sentences: • • Co-occurrence constraints • If you have one word somewhere in a sentence, you must also have another word somewhere else in the sentence.
