Morphology Building meaningful words

What is a morpheme? Linguistic unit with Can be (more or less) constant meaning (more or less) constant form Combine to create “words” Can be Content (Lexical) or Functional (Grammatical) Free or bound If Bound & Functional: Inflectional or Derivational

Content function PRESS VERT From Parker & Riley, 2010: Linguistics for Non-linguists

Constant meaning E.g., plurals = more than one: written as “{PLU}” Noun + {PLU} = Noun + “s”: “Cats” = more than one cat; Dogs = more than one dog, etc. BUT: Man + {PLU} = Men = more than one man. More or less constant form NOTE: to help identify them, sometimes morphemes will be presented inside of brackets like this “{ }”.

Content or function Content = means something on its own Content words. Noun, Verb, Adjective, etc. Function/Grammatical = express relationships between other morphemes Function words. Preposition, Determiner, Conjunction, Copula, etc. If you don’t know these terms, we’ll get to them soon.

Free or bound Free = can stand alone as a word Can be content (cat) or function (and) Bound = always part of another word Can be content ({clude} as in exclude or include) or function ({PAST} as in Excluded)

Function/ Grammatical Morphemes Their meaning involves some relationship between or character of content morphemes. NOT related to their status as “word” Free morphemes But – contrast between things on each side The – known and specific entity follows Bound morphemes {PLU}, {POSS} etc…

Derivational or Inflectional One per word and always suffixes (sort of) Wide application Follow derivational in the word (usually) Don’t change syntactic category of the word E.g., can’t change a noun to a verb Dog + {PLU} = “dogs”, which is still a noun. Derivational More than one allowed, can be prefix or suffix Can change the syntactic category of the word

Fixes: Pre Prefixes come before the word. In English they are derivational morphemes e.g., precede = “{pre} + {cede}”, Unclear = “{un} +{clear}”, Decline = “{de} + {cline}”

Fixes: Suf Suffixes come after the word. Most English inflectional morphemes are suffixes and all can be represented as such Heavier = {heavy}+ {COMP} Men = {man} + {PLU} I run_ / he runs = {run} + {PRES} There are also derivational suffixes, of course.

Fixes: In Infixes come in the middle of the word Hizouse (true infix, limited dialect) - archaic? Chemical names have true infixes. “pe” and “et” Abso-frackin-lutely (“tmesis”) _don’t memorize this term Man to men; drink to drank (“apophony”) _don’t memorize this term

The Big 8 – English Morphology Inflectional , that is.

The big 8: Inflectional Morphemes PLURAL {root noun} + {PLU} = boys; men, sheep. Note that some irregulars need syntactic information to be identified. “These sheep are…” versus “This sheep is…” “Those fish have…” versus “That fish has…” This works because plurality also impacts the form of other words in the utterance “Agreement” rules show up in {PRES} (is versus are) and the choice of demonstrative…(i.e., “This/These/Those/That” ) We’ll get back to this topic

The Big 8 Possessive: {root noun*} + {POSS}: pretty regular John’s, dog’s, horse’s Plural possessives get tricky…but syntax helps, again. The horses Horses = {horse} + {PLU} The horses’ saddles were crooked. Horses’ = {horse}+ {PLU}+{POSS} BUT WAIT – rule: one inflectional morpheme per word. *Technically {POSS} applies to the noun phrase, not the noun. E.g., pronouns/proper nouns His/her book was read. {S/he} + {POSS} Bob’s book was read. . {Bob} + {POSS} In multiword Noun Phrase, it will be the noun to which {POSS} attaches. The race horses’ saddles were crooked. This makes it look like there are TWO inflectional morphemes in “horses’” Man + {PLU} + {POSS} , but it is really NOUN PHRASE + {POSS}

The Big 8 Comparative: {root adjective} + {COMP}; let’s us know that there is “comparatively more”. Some are irregular. Big becomes bigger = {big} + {COMP} Good becomes better = {good} + {COMP}. Beautiful becomes more beautiful Not an affix and before the adjective. Maybe this is really more syntax Comes from “more full of beauty”

The Big 8 Superlative: {root adjective} + {SUP}; big becomes biggest let’s us know it is at the pinnacle of the trait. Some irregularity. big becomes biggest good becomes best Beautiful becomes most beautiful. Again, syntax or morphology? Comes from “most full of beauty”

The Big 8 Present tense: {root verb} + {PRES} Typically no change in the root I/You/We/They kick the ball kick = {kick} + {PRES} When subject is 3rd person singular, affix is attached. He/She/It/John/Mary/The dog kicks the ball. kicks = {kick} + {PRES} Note = same form as {PLU}, but not there when {PLU} is there The dogs kick_ the ball A few irregulars. be: I am, you are, we are, they are, he is do (and compounds such as "undo" and "redo"): I do, you do, we do, they do, he does have: I have, you have, we have, they have, he has.

The Big 8 Past tense: {root verb} + {PAST} Typically a suffix, but there are many irregulars (some using apophony = infix, change in vowel) walked, drove, thought, drank, etc… Always transcribe as a suffix {walk}+ {PAST}; {drive}+{PAST}; {think} + {PAST}

Complexities and tense If there is more than one verb in a string, which verb gets to have {PAST}? The LEFT most verb. Compare “I did drive/think/walk” to “I drove/thought/walked” Compare “I was driving” to “I drove” - etc. Others “She did not go with me last week” vs. “She went with me last week” “We did not work yesterday” vs “We worked yesterday” If there is more than one verb, which verb gets {PRES}? Compare “I drive ”/ “He drives” to “I am driving”/ “He is driving” Compare “He works today” to “He is working today”

The Big 8 The Participles Similar to verbs & adjectives English has two: Past and Present. The present participle in English is entirely regular (__________ing). But not all (__________ing) are present participles. The past participle is very complex, morphologically. i.e., it comes in a lot of different shapes.

The Big 8 Present Participle {root verb} + {PRES PART} Perfectly regular: {PRES PART} is used like this: John is helping/ They weren’t helping/ I will be helping. To form the progressive tense - use the appropriate form of to be from the present/past/future tense and put the present participle after. Notice…the LEFT most verb gets the tense. The sleeping student snored. (a noun modifier) Broadly speaking, the project was successful. (a clause modifier). NOT “gerunds” (which are “ing” nouns). John’s sleeping put him way behind. {sleep} + {GERUND} YOU SHOULD BE ABLE TO TELL THE DIFFERENCE By what they do in the sentence

The Big 8 Past Participle: {root} + {PAST PART} Usually the same form as the past tense version of the verb. Many irregulars In simple active sentences, follow “have” They have walked home. In passive sentences, follow “to be” or “got” It was given to her It got broken in the move.

The Big 8 More on {PAST PART} modifying a noun, modifying a sentence: Our fallen comrades did not make it through the test. The attached grades show who has died Can follow the noun as well. The test questions encountered were fatal to some. modifying a sentence: Seen from this perspective, the grades were deadly serious.

Inflectional morphemes & syntax From the big 8 Noun-only: {PLU}, {POSS}* * noun-phrase, really. Adjective-only: {COMP}, {SUP} Verb-only: {PAST},{PRES},{PAST PART}, {PRES PART} The presence of the inflectional morpheme tells you the syntactic category of the word. We’ll get back to these concepts later, but morphology is influenced by a higher-level of organization, syntax. One reason many language scientists hypothesize that the correct organization of language would include a single structure called “morphosyntax.” Based on the idea that morphology and syntax are inextricably linked.

Inflectional morphemes & syntax Inflectional morphemes can give us a hint about what syntactic slot a word is in. The heavy/heavier book was red. An adjective = weighty The heavy’s book was red. The heavies’ books were red. Can’t be an adjective, only nouns take {PLU} & {POSS} Must be a noun: “Heavy” = “mobster muscle”; or “important person”

Inflectional morphemes & syntax Distrubution + moprhology. The heavy/heavier book was red. The big/scary/informative/ book was red. Other adjectives fit into the slot, can take {COMP}. The heavy’s book was red. The heavies’ books were red. The children’s books were red; Bob’s books were red; Their/Her/Its books were red Other noun phrases fit in the slot The morphology will be consistent with other words that could fit in that place in that sentence. The words will have a similar distribution. A concept we will return to when we talk about syntax.

Derivational Morphemes A quick discussion

Derivational Morphemes Too many to go over in detail. Grammatical, bound, can be prefix, suffix, or infix Can change grammatical category (don’t always). Theory to Theoretical (noun to adj) Theory to Theorize (noun to verb) Theoretical to Atheoretical (Adj to different Adj) A word can have more than one, unlike inflectional morphemes Note: {PLU} for noun {POSS} for NP

Other Differences Historical development Range of application – some are very narrow Order of appearance Derivational suffixes precede inflectional suffixes (generally: {Universe} + {al} + {PLU} = Universals Not Universesal = {Universe} + {PLU} + {al} Exceptions to this rule are tough to interpret, but typically can be explained away Spoons full → Spoonfuls; Mothers-in-law → Mother-in-laws.

Clinical Use of Morphology Reading: Brown, 1973

Roger Brown Wanted to know how children develop language Did careful analysis of a set of 3 children Identified 14 grammatical morphemes that were revealing of language development Useful for understanding a child’s progression towards adult grammar

Brown’s 14 morphemes Present Progressive Tense Marker {Pres Part} Notice that some of the big 8 are broken up into regular and irregular forms, or their use restricted to a particular function. e.g., {Pres Part} as a modifier is not included. From: Retherford (2007) Guide to Analysis of Language Transcripts, 3rd Edition.

Not in the Big 8 (exactly) “ing” - {Pres Part} as a modifier is not included. prepositions “in” and “on” Articles “a/an” “the” – free, grammatical morphemes that impact “definiteness” and “specificity” “Copula” – linking verbs such as “is” or “acts” or “seems” (i.e., He is fine. He seems fine. He acts fine.). Auxiliary verbs (i.e., “is/was _______ing” as in “He was/is jumping”)

Contractible or not Copula and Auxiliary verbs may or may not be “contractible” Contractible Auxiliary: He’s jumping vs. He is jumping; They’re jumping vs. They are jumping. Contractible Copula: He’s fine vs. He is fine. Uncontractible Auxiliary: He was jumping, They were jumping. Uncontractible Copula: He was fine. He acts fine. He seems fine.

Obligatory Context Brown determined “development” by comparing to adult expectations. Does the child use the morpheme in places that an adult would be expected to use it? Requires a clinician to recognize obligatory contexts for these morphemes. Let’s look at some examples

Obligatory Context A child that fills these contexts with the appropriate morpheme will have longer, more complex utterances. Counting that complexity can reveal something about their knowledge of the language And this may tell us something about their ability to learn

Brown found that Complexity of language could be measured based on how many morphemes are included in an utterance Mean Length of Utterance in Morphemes MLUm Used specific, developmentally based rules to count these morphemes. Derivational morphemes are not counted. Might be an interesting thing to do with much older children.

Brown1973 .

Morphological impairment A morphological impairment indicates reduced knowledge about word shapes resulting from an inability to learn that knowledge Limited use of obligatory forms Increased error (using form in incorrect context) Opportunity to learn must be assessed
