What Does It Mean to Know
a Word? • The word’s sounds and the sequencing of these
sounds
• The word’s meanings
• The word’s category and how to use it in a
sentence
• How the word can be changed into related words in
the grammatical system
– All of this information is stored in our lexicon

• Morphemes can have lexical or grammatical meaning
• A morpheme is not the same as a syllable – river and gorilla are multisyllabic but
monomorphemic
– kissed and dogs are monosyllabic but have more than one morpheme
What is a morpheme?
• The smallest meaningful unit of language
• It cannot be further analyzed into smaller
meaningful parts
• It has a similar meaning or function
wherever it appears.
– tourists

Organization of Morphemes--
Types of morphemes
• Morphemes are classified into four types based on their
position within a word. Some morphemes are organized
linearly but some are discontinuous
– Organized linearly
• Affixes: Prefixes and Suffixes
• Infixes
– Organized discontinuously
• Circumfixes
• interweaving
• Morphemes are classified into two types based on
their function in language.
– Derivational
– inflectional
Language: Its Structure and Use
Language: Its Structure and Use
Organization of Morphemes • Suffixes: follow the stem
• girls, commitment, simplify
• Examples from Turkish:
dur “to stop” durak “stopping place”
bat “to sink” batak “swamp”
• Examples from Newar :
na “eat” nakāl “caused to eat”
bo “fly” bokāl “caused to fly”
niŋ “count” niŋkāl “caused to count”
The suffix –kal is a causative marker.
prefixes
• Prefixes: come before the stem • untrue, disappear, repaint
• Examples from Isthmus Zapotec (Mexico)
zigi “chin” kazigi “chins”
zike “shoulder” kazike “shoulders”
diaga “ear” kadiaga “ears”

• Abagatan ‘south’ tagaabagatan
‘southerner’
• ili ‘town’ tagaili ‘from town’
• Amerika ‘America’ tagaamerica
‘American’
• The prefix taga- means ‘from’ indicates origin.
Infixes
• Infixes: inserted in another morpheme
– Tagalog: gulay (‘greenish vegetables’)
ginulay (‘greenish blue’)
Agta (Phillipines)
darág ‘red’ dumarág ‘become red’ (d+um+arag)
furáw ‘white’ fumuráw ‘become white (f+um+uraw)
dakal ‘big’ dumakal ‘grow up’ (d+um+akal)
Language: Its Structure and Use
Infixes?
• Caution:
• Not an infix
– darkens
– lightens
– flattens
– A sequence of suffixes
• dark-en-s
Circumfixes • Morpheme that occurs in two parts, one on each side
of the stem
– Malay-Indonesian: baik (‘kind’) / kebaikan
(‘kindness’)
– Ilocano: ragsak ‘happy’
• pagragsaken ‘make someone happy’
pag-ragsak-en
uray ‘wait’
pagurayen ‘make someone wait’

Dutch (Hana 2011)
• berg 'mountain' gebergte `mountain range'
*geberg, *bergte
• vogel 'bird' gevogelte `poultry'
*gevogel, *vogelte
• The circumfix ge- -te adds the meaning of
collectivity

Organization of Morphemes • Interweaving morphemes:
• Stem K-T-B
Discontinuous morphemes in
Arabic Root = Q-T-L
Qatil “killer”
qatl “killing
qutila “be killed”
qatal “kill + perfective
yaqtul “kill + imperfective

salam “peace”
aslam “to submit”
musal “undisputed”

Status of morphemes in
different languages • Languages may differ in how they use affixation
• What is a prefix in one language may be a suffix in another
• Isthmus Zapotec plural prefix ka-
• What is an affix in one language may not be expressed with
affixation in another
• English dance (N) and dance (V)
• What is a separate word in one language may be an
affix in another.
Nepali khanechu “I will eat” (-chu = future)
Morphemes
• Derivational morphemes:
– Change the lexical category • Noun + -FUL = Adjective
• doubt + -ful = doubtful
– Change the central meaning
• align/realign, fair/unfair
• Inflectional Morphemes:
– Do not change lexical category or central meaning • cat-s, collect-ed, sleep-s, and loud-er
Language: Its Structure and Use
Derivational Morphemes
• Derivational affixes change lexical (syntactic) category change, derives a new word:
solid solidify adjective verb
govern government verb noun
sublime sublimity adjective noun
fame famous noun adjective
Derivational affixes: no change
in lexical category Adj. -> Adj.
accurate in-accurate
kind un-kind
honest dis-honest
Noun -> Noun
mayor ex-mayor
gang gangster
prank prankster
Verb -> Verb
approve dis-approve
tie un-tie
write re-write
• words with new
meanings are created
Inflectional morphemes
• These morphemes combine with a word to change the grammatical function of the word.
–Plural table + s
–Comparative tall + er
Provides grammatical information (person, number, gender, case, tense)
• Consider the sentence:
John hate-s Mary
• -s marks the 3rd person
singular present form of the
verb
• It relates the verb to the 3rd
singular subject John
• hates = hate + s
English Inflectional
morphemes
Verbs:
talk-s 3rd singular present tense
talk-ed simple past
eat-ing present participle
eat-en past participle
English Inflectional
morphemes • 3rd person, singular –s
– John walks
• Past tense –ed
– John walked
• Present participle –ing
– John is walking
• Past participle –ed/-en
– John has walked
– John has eaten
English Inflectional
morphemes • Nouns
– Dog-s Plural
– Six books
– Dog-’s Possessive
– John ‘s book
English Inflectional
morphemes • Adjectives
– big
– bigg-erComparative
• John is taller
– bigg-est Superlative
• John is the tallest student in the class.
Order of inflectional and
derivational morphemes in words
• nationalizations
• nation is a noun
• nation + -al is an adjective
• national + -ize is a verb
• nationalize + -ation is a noun
• nationalization + -s is the plural inflected form of a noun
Derivational vs. inflectional
affixes
• In English, derivational morphemes can be
either prefixes or suffixes
• Inflectional morphemes are always suffixes
• re- + organize reorganize-s
• simple + -ify simplifi-ed
Organization of morphemes:
Internal Structure of Words
Morphemes are layered within words: Although
the morphemes are organized linearly, they have a hidden hierarchical structure :
• Morphemes are added to a base in a fixed order
which reflects the structure of a word
• Words are constructed hierarchically
• One affix is attached to the root first
• Derivational morphemes attach before inflectional ones
Two important facts
• Two important facts for determining the steps by which words with more than one affix must be formed:
– Affixes attach to certain lexical (grammatical) categories
• -able attaches to verbs but not nouns or adjectives: readable, doable, breakable; *catable, *greenable
• -ish to nouns: girlish, selfish; *readish, *breakish
– Affixes can determine the lexical category of a word
• Words that end in –able are adjectives (washable, stoppable)
• Words that end in –ness are nouns (unhappiness, attractiveness, hopelessness)
Words have layers, like
onions
• Educate (verb)
• Educat-ion (verb > noun)
• {Educat-ion}-al (noun > adj)
• {{Educat-ion}-al}-ly (adj > adverb)
Words have layers, like
onions
[ [ [ Educat – ion] – al] –ly]

Morphological Systems • Isolating morphology (e.g., Chinese)
2. nî deng wo, wo jiu gen nî qu.
2SG wait 1SG 1SG then with 2SG go
‘If you wait for me, I will go with you.’
– Words are single morpheme
– No derivational and inflectional morphology
– Grammatical information is expressed by word order
Isolating morphology
Hmong (Laos):
Tus neeg caum nqai tau xuas
the person chase game attain grasp
phom tua tus noog los gun kill the bird past
‘The hunter killed the bird with a gun’
Morphological systems
• Agglutinating morphology
• Words can have several prefixes and suffixes that can be
segmented into parts
– A single word may have several bound morphemes
– Words can be easily broken into distinct morphemes
– Each morpheme has only one distinct meaning
– Turkish, Swahili, Nahuatl and Japanese, among others
Turkish
• evjiklerimizde
• ‘in our little houses’
•ev-jik-ler-imiz-de
• house-little-plural-possessive-in

Morphological systems Inflectional morphology (e.g., Russian)
–Grammatical functions expressed in
morphology
–Large inventory of inflectional morphemes
–Morphology organized into paradigms
–more than one meaning fused into a single
affix
–Case systems, gender, and agreement
Declensions and
Conjugations
• The set of forms showing the inflectional
variants of a word is called a paradigm.
• Paradigms for nouns are called
declensions.
• Paradigms for verbs are called
conjugations.
