What is a pidgin
simple language for communication between groups without a common language
what is a creole
: pidgin that becomes a native language for the next generation
what is phonology
Phonology refers to the speech sounds of a language
What are phonemes
Phonemes are sounds that signal differences in meaning
What are minimal pairs
(two words with different meanings that differ only in one phoneme)
Bat Pat /b//p/
Pick Pill /k/ /l/
Pin Chin /p//ch/
Zoo Sue /z//s/
What is morphology
Morphology refers to the meaningful forms of a language
What are morphemes
Morphemes are forms associated with units of meaning
What is un-prefixation
adding ‘un’ to words changes the meaning
What is syntax
Syntax refers to the rules that control how words are ordered
Rules of syntax operate on constituents (e.g., Noun Phrase) not words
Passive syntactic rule
NP VERB NP -> NP IS VERB BY NP
What are semantics
Semantics refers to the meaning of words (concepts) and sentences
Quine (1960): “gavagai”
Children need to understand others mental states ( the context) to understand the meaning of these words
What are pragmatics
how language is used in context to convey meaning
What do studies of animals like dogs, Alex the parrot, and Kanzi show about animal language abilities?
Arbitrary associations:
Animals like dogs can learn word–meaning pairs quickly.
Compositionality:
Some animals combine meanings—Alex the parrot understood “red ball,” and Kanzi the bonobo followed new sentence structures.
Limitations:
Their communication isn’t fully symbolic; they mostly use signs to get things, not to share ideas, and they don’t use social language.
describe variations in speech sounds - free variation
When two sounds (like the /t/ in hot) can be pronounced differently — aspirated or not — without changing meaning.
but in other languages-
In Zulu, aspirated [tʰ] and unaspirated [t] are different phonemes, meaning they change word meaning.
What is contextual variation, and how does it differ across languages?
Contextual variation: When the pronunciation of a sound changes depending on nearby sounds.
In English, /k/ varies by context:
keel → fronted /k/ (toward the front of the mouth)
cool → backed /k/ (toward the back of the mouth)
These are allophones of the same /k/ phoneme.
In Arabic, the front /k/ and back /k/ are distinct phonemes — changing them changes the meaning of words.
What are phonemes different to
not the same as letters as writing systems use different letters to express same phonmes.
what is inflectional morphology
does not change the syntactic category or meaning of the word
Dog + s DOG + PLURAL
Jump + ed JUMP + PAST
what is deprivational morphology
Derivational morphology can change its syntactic category or meaning
Un + cover REVERSE + COVER
Sad + ness SAD + STATE -> noun
What does the replacement rule test show? for syntax
What does the replacement rule test show?
A: If one group of words can replace another, they’re the same constituent.
Example:
Some boys are bigger than others → They are bigger than them
Shows some boys and they are both noun phrases (NPs).
What do syntax rules specify?
What forms constituents (like NPs) can take.
How they combine to form sentences.
Examples:
NP → Proper Noun → Fido
NP → Det + N → The dog
NP → Det + N + PP → The dog with the huge teeth
S → NP + V + NP → [The dog] bit [the postman]
What is recursion in syntax, and why is it important?
Recursion in syntax is when a grammatical rule can apply to its own output — meaning the rule can call itself to create larger and more complex sentence structures.
Key idea: A finite set of words and rules can generate an infinite number of sentences.
