Lecture 3: Morphology

Review + homework for next week

Write 1-2 pages about:

  • Phoneme inventory: What segments (= primitive signals) are valid in your language?
  • What sequences of seqments are available in your language?
    • If your language is a spoken language, describe them in terms of syllables
    • If not, do you want to put (phonological) restrictions on possible sequences? Note that there will be morphological and syntactic constraints.

Today: Morphology

Once we have the segments/primitive signals, the next step is to form meaningful expressions out of them (= morphemes/words)

Morphology is about:

  • Morphological structure and paradigms (networks of related words)
  • Morpho-phonological rules

A lot of arbitrariness, but there are still some principles

What is a word?

It's notoriously difficult to give a general definition of what a word is

  • For some languages (e.g., English, Japanese, Uyghur), it's possible define the phonological word phonologically (e.g. in terms of accent domain, vowel harmony)
  • But such a definition might not apply to languages with different prosodic properties (e.g., French, Mandarin Chinese)
  • It also does not perfectly match the morphological word, e.g., for 'at a university', morpho-syntactically we might want to say three words, but only one primary stress

As Haspelmath (2011) argues, there's no single typologically applicable definition

What is a morpheme?

A morpheme is said to be the smallest meaningful expression

  • /kæt/ is a morpheme
  • /kæts/ is bimorphemic

But not everything is so easily segmentable

  • zero morphology: book in Russian (Wikitionary)
  • ablaut: /rɪŋ/ vs. /ræŋ/ in English, see next slide for Dinka

'Kick' in Dinka

Words and morphemes for your language

  • No need for a general definition of words or morphemes that applies to all languages

  • But you might want to define such terms for your language

    • So-called 'isolating' languages (e.g., Vietnamese) have little morphological structure; (almost) every morpheme is a word
    • We could have non-trivial morphological structure in non-spoken languages

Later, you'll be asked to make some words (based on the Leipzig-Jakarta word list)

Principles behind words/morphemes

Zipf's law

Zipf's law: Word frequency is inversely proportional to rank (e.g., the most frequent word is twice as more frequent as the second most frequent word)

Zipf-Mandelbrot law for a better fit (e.g., , ):

see Wikipedia and Piantadosi 2014 for graphs

Brevity law

The brevity law (Zipf's law of abbreviation): More frequent words tend to be shorter

Minimal words

Some languages have minimal word requirements, e.g. according to Van Urk (lecture notes) nouns and verbs in Imere must have three syllables

This is arguably related to stress (primary stress falls on the antepenultimate syllable in Imere)

Morphological structure

Morphological processes

  • Concatenative morphology

    • Affixation (suffix, prefix, infix, circumfix)
    • Compounding
  • Non-concatinative morphology

    • mutation (ablaut; consonantal, e.g., Welsh)
    • Subtraction
    • Reduplication
    • Portmanteau
    • Templaic morphology (see next slide for an example)

Allomorphy

Morpholological processes create related words

Allomorphy: The same morpheme might be relalised differently in the same paradigm

  • /haʊs/ 'house' vs. /haʊz/-/ɪz/ (hous-es)
  • /ɛɡeːr/ egér 'mouse' vs. /ɛɡɛr/-/ɛt/ eger-et 'mouse-acc' in Hungarian

An extreme case of this is suppletion, e.g.

  • go vs. went
  • person vs. people
  • good vs. bett-er vs. be-st
  • va-i (go-2sg.pres.ind) vs. anda-te (go-2pl.pres.ind)

Morphophonological rules

Allomophy may involve phonologically conditioned alternations, e.g.

  • Assimilation (e.g., in- vs im- in English)
  • Dissimilation (e.g., -ālis vs. āris in Latin)
  • Vowel harmony (e.g. mektep-te 'school-loc' vs. yighin-da 'meeting-loc' in Uyghur)
  • Neutralisation (e.g., /bɛt/ 'bed' vs. /bɛdə(n)/ 'bed-pl' in Dutch; cf. /boːt/ 'boat' vs. /boːtə(n)/ 'boat-pl')
  • Epenthesis
  • Deletion

See Odden 2005 for more examples

Natural phonological rules

  • Arguably many phonological rules apply to solve phonetic/phonological issues (e.g., neutralise in perceptually less contrastive positions, break consonant clusters, etc.)

  • The phonological change tends to be minimal

Impossible morphophonological rules:

  • A neutralisation rule that applies to stressed syllables
  • Prefix /in-/ becomes /akof-/ if the following segment is labial

Morphology for your language

  • Your language can obey or disobey the brevity law

  • Your language can be morphologically simple or complex

    • If it can be morphologically complex, decide what kind of morphological process to use
    • Decide if they should involve morphophonological rules

You'll be asked to make some words and morphemes before Week 5
