Semantics
3a. Word meaning
3.1-3.6ish
Lexical semantics
• As a first approximation: The meaning (and
relations between the meanings) of words.
• Pat is a bachelor.
• Pat is a man.
• Pat has an unpleasant personality.
• My sister is a bachelor.
• Tracy fed my dog.
• My dog ate.
• My dog is no longer hungry.
Lexical semantics
• What is it about bachelor that tells us (necessarily,
inescapably) about maleness? What is it about
feeding that tells us about eating?
• Bachelor and male share something in common—
to be male…and to be unmarried.
• (And probably to be otherwise eligible to be married)
Lexical semantics
• Our knowledge
about the words
(and
morphemes) of
language can be
thought of as a
list, as a “mental
dictionary”—a
lexicon.
Bachelors and men
• If Pat is a bachelor, and to be a bachelor is to be a
man and to be unmarried (and possibly to be
eligible), then it follows that Pat is a man, that Pat
is unmarried but eligible to be married. So, we
have learned something about the meaning of
bachelor and its relation to the meaning of man.
• Pat is a bachelor entails that Pat is a man.
• Entailment: X entails Y if there can be no situation in
which X is true but Y is not.
Entailment and other reasoning
• Pat is a bachelor.
• Pat has an unpleasant personality.
• Pat has an unpleasant personality is not a
necessary consequence of Pat is a bachelor. The
first does not entail the second.
• It could be that Pat has joined a priesthood, it could be
that Pat has unrealistically high standards, it could
be…well, it could be any of a number of things.
Meaning and lexemes

• Lexicon = repository of unpredictable information.

Grammatical category
(Linked to) encyclopedic knowledge, register,
frequency.
• …
• We may think of this in terms of lexemes, insofar
as kick, kicked, kicks, kicking have a predictable
part and an unpredictable part to their meaning.
The dictionary/lexicon need list only (to) kick.
A lexeme is more abstract than a
“word”
• And what is a “word” anyway?
• We can come up with some more or less arbitrary
definitions, but they don’t seem to get us much
closer to understanding how the lexicon and
semantic system is structured.
•
•
•
•
•
A word has spaces written around it. (isn’t vs. is not?)
A word can stand alone (*the, *a)
A word is pronounced separately (dyoowannaeet?)
A word expresses a concept (again, *the, *although)
…
What is a “word” anyway?

• ‘Someone did not find a completely suitable resting place.’

Bigger vs. more expansive vs. *expansiver.
“I’m afraid she’s gone and Michael Jacksoned herself to
the point where she doesn’t even appear human
anymore” (some random comment on some random blog, referring to
California gubernatorial candidate Angelyne. Google “michael jacksoned” if you
One “word” several lexemes
• bank1 : side of a river.
• bank2 : financial institution
• One word, (at least) two senses, two lexemes.
• The word bank is ambiguous—it could mean
‘bank1’, it could mean ‘bank2’. This is different
from vagueness, for example with large, small
(Mickey is large, Willy is a small), or student
(John, Mary) with respect to gender.
Differentiating ambiguity and
vagueness
• One way is with verb phrase ellipsis:
• Tracy ate a sandwich and Pat did too.
• Tracy ate a sandwich and Pat [ate a sandwich] too.
• Pat visited a bank and Tracy did too.
• Pat visited a bank and Tracy [visited a bank] too.
• John is a student and Mary is too.
• Mickey is large and Willy is too.
Dimensions of relatedness
• Bank1 (the river-side) and bank2 (the financial
institution) are homonyms. Two basically
unrelated words that sound the same. And are
written the same. And are pronounced the same.
• Subdivisions are possible: homographs are written the
same, homophones are pronounced the same. They
(very well) might vary by dialect (bury, berry, Barry;
Mary, merry, marry). They might share a category
(wring, ring) or not (knot).
Polysemy
• Where different senses are judged to be
related, we have polysemy rather than
homonymy. Sometimes a tough call.
• Bat1 : implement for striking in certain games
• Bat2 : furry mammal with membranous wings
• Sole1 : A sort of flat fish
• Sole2 : Bottom of a foot or shoe
• < solea (Latin) via French.
Synonymy
• A thesaurus provides synonyms—different words
that share (nearly) the same meaning.
• True synonyms may not exist, there is pretty much
always a difference in register, attitude, dialect,
collocation, or lexical relations.
•
•
•
•
Lawyer, attorney, counsel, …
Couch, sofa, futon, …
Little sister, small sister, …
Police, cop, pig, fuzz, …
Antonyms
• Antonyms are in opposition, and come in a
number of different flavors.
• An animal might be alive or dead, but not both.
You might pass or fail a test, but not both.
• Though we can make sense of undead and half-dead in
fanciful ways.
• Reversing the perspective: come/go,
ascend/descend, up/down, in/out (reverses for
motion, converses for more static relations)
above/below, before/after/behind.
Antonyms
• The opposition can be gradable as well.
Something that is not hot is not necessarily
cold, but they are still in opposition.
Beautiful/ugly, fast/slow, tall/short,
large/small.
• Or, they can be opposed in a non-binary
way (taxonomic sisters): red/green/blue,
January/September/November/December.
Hyponymy
• Some words are related in an
inclusion relation.
• Couch, furniture.
• Capybara/mammal/animal.
Meronymy
• Meronymy: Part-whole relations:
• Word/sentence/paragraph/page/chapter/book
• Member-collection: boat/fleet, bird/flock
So where are we?
• The meanings of words (ahem, lexemes) are
related to each other in many different
ways. Some relations are prominent enough
to be classified (synonyms, antonyms,
hyponyms, polysems, …).
• An empirical result of these connections can
be seen in our inference patterns.
• Fido is a dog. Fido is a mammal. Fido is a cat.
What we know
(about English, say)
• Part of an English-speaker’s knowledge of
language is the information in the lexicon:
lexemes, their pronunciation, their syntactic
category, their relationships to other
lexemes, … and whatever is left, that we
might call their meaning.
Back to the question of “words”
• We might imagine that we can come up with some
kind of “meaning” (definition, say) for tie or wrap.
• We might observe that the relation between untie
to tie rather like the relation between unwrap and
wrap. And we might observe that one is simply the
other plus un-.
• Words themselves are composed of morphemes,
some of which are meaningful in and of
themselves (and would have lexical entries of their
own).
Derivational morphemes
• So, alongside the content words like likely we
have derivational morphemes like un-, together
combining to form a word (with a predictable
meaning) unlikely.
• Recall: unrefaxeristically.
• Or: antidisestablishmentarianism (opposition to the
disestablishment of the Church of England)
• These (anti-, dis-, -ment, -ary, -ian, -ism) are
lexemes in their own right.
• Finding the morphemes isn’t trivial (ally, prism,
canary, cement, distant), but they do seem to exist.
Inflectional morphemes
• Derivational morphemes like iN- (impossible, irregular,
incapable, intractable) are often distinguished from
inflectional morphemes (walk, walks, walked) in that
derivational morphemes carry a heavier semantic load.
Inflectional morphemes are agreement (with, e.g., a 3sg
subject).
• Practically, it’s a difficult line to draw precisely, but generally
grammatically enforced morphology (agreement, tense/aspect
marking) is in the “inflectional” category. Some linguists in fact
argue that the distinction isn’t a meaningful one, but that isn’t
the consensus view.
Derivational morphology
• Derivational morphology is also capable of
changing a word’s category.
• The road is wide. (adjective)
• The road widened. (verb)
• He refaxed the memo. (verb)
• He is a refaxer. (noun)
• He acted in a refaxeristic manner. (adjective)
• He acted refaxeristically. (adverb)
Causatives/inchoatives
• A reasonably large class of verbs seem to be
able to alternate between inchoative (change
of state) verbs and causative verbs.
• The door is open. (adjective)
• The door opened. (verb; inchoative)
• I opened the door. (verb; causative)
• I sank the boat, I melted the chocolate.

(invented)
obnogtem ‘you feed’
obgilte ‘he causes to beat’
obudtem ‘you cause to drink’
Causatives
• There are languages that have a causative
morpheme that derives feed from eat.
• English has some too, which come out
differently depending on the specific word:
• We enlarged the photograph.
• We modernized the house.
• We opened the door.
Open v. open
• How does open in The door opened relate to
open in I opened the door?
• Perhaps there’s a “hidden causative” in I
opened the door (like the “hidden plural” in
I saw two deer). A prefix (or suffix) that has
no pronunciation? I Ø-opened the door.
Kill vs. die
• Consider too the relation between kill and
die. What do the semantic components of
kill seem to be?
• The surface (pronounced) form of a word
may not fully reveal its underlying semantic
structure.
“Lexical decomposition”
• We might think of kill as CAUSE-die, of
enter as CAUSE-BE-in, of give as CAUSEHAVE.
• So semantically, Tracy gave Mary a book
might really be Tracy CAUSE Mary HAVE
a book.
Kicking the bucket
• Sometimes whole phrases (verb phrases) can have
an idiomatic meaning: kick the bucket, buy the
farm, … They have a meaning that is not derivable
from the component parts.
• Usually, this is tied to both the verb (tap the
bucket, rent the farm) and the object (kick the pail,
buy the house) together.
Something to ponder
• Interestingly, there are some idioms that seems to allow a
certain flexibility:
• Tracy gave Pat the boot.
• Pat got the boot.
• But it isn’t unlimited:
•
•
•
•
Tracy gave the boot to Pat.
Pat has the boot.
Pat took the boot.
The boot ruined Pat’s Christmas.
• We’ll kick off next time with a somewhat involved
argument from this that give, get, have (, take), all have
HAVE as a “silent component.”
