How do verbs like "give" and "put" juggle more than one object? Is there an element that lets verbs cause things to happen? In this episode, we talk about splitting up the verb phrase: how our basic syntactic theory has a hard time with verbs with more than one object; how the syntax of causation shows us why we should expand our trees; and how once we break the phrase up, we can capture all sorts of facts, from two-object verbs to ambiguities.
What's the difference between "thinking" and "knowing"? What rules do we follow for adjusting our conversational worlds? In this episode, we delve into the semantics and pragmatics of presuppositions: which words come equipped with them, how presuppositions depend on the situation and our mental worlds, and what antipresuppositions can tell us about the mechanics of interpreting sentences.
How do sentences fit inside other sentences? Where can we put words like "that", "whether", and "if"? In this episode, we take a look at complementizer phrases: what exactly they are, how they account for embedded sentences and questions, and what they can let us do to capture word order in languages like German and Dutch.
What kinds of sentences do we hear from babies and toddlers? How much grammar can we find in their language use? In this episode, we take a look at child syntactic stages: what characteristics kids display as they progress from one to two to many words, whether their grammars are similar to those of adults, and how their linguistic interpretation may tell us more than just their speech.
What roles do nouns play in sentences? How can we figure out those roles when they get moved around? In this episode, we talk about case: how nouns get case, how it explains why some sentences are okay and others not, and how it can even help account for different word orders between languages.
How do we combine words to build full propositions? How do we account for what people believe, not just what's definitely true? In this episode, we talk about type theory: how we can define terms by how they relate to the world and each other, what the difference is between sense and reference, and how we can use possible worlds to work out what people believe.
How can we try to capture the commonalities and differences between linguistic sound systems? What makes one language sound different from another? In this episode, we take a look at Optimality Theory: how we can use constraints to describe how phonology behaves, how we rank which rules we care most about breaking, and how changing our priorities leads to totally different sound outcomes.
What basic properties do all human languages have in common? How might languages from other worlds differ? In this episode, we take a look at potential alien languages: how we can categorize them differently from how our languages work, how they could potentially make sounds and compose meanings, and how imaginative we may have to be to understand what other species might have to say to us.

In this episode, we take a look at the acoustics of nasal and approximant consonants: how opening up your nose influences your speech, how close some consonants are to being vowels, and why it can be hard for some people to tell apart the English l and r.
How do we show possession in our syntax? And what does that tell us about representing nouns in our trees? In this episode, we take a look at determiner phrases: why we need them on top of noun phrases, how they turn some of our ideas about syntax inside out, and what they let us display in trees that we couldn't before.
What knowledge do you start off with when you learn a third (or fourth, or fifth...) language? Do the languages you already have in your head help or interfere? In this episode, we talk about third language acquisition: whether you have to transfer from your first language, how you can build from the languages you already know, and what we still don't know about this new field.
What goes into making a sentence? How has our view of the sentence changed over time?

Why do different languages slot their words into sentences in different sequences? Do the subjects of sentences have to start off at the beginning of the sentence? In this episode, we talk about word order and the Verb Phrase-Internal Subject Hypothesis, or VPISH: how much variation in orders we see across languages, why having the subject start out lower down in the syntactic tree helps us capture these differences, and what other evidence we have that the subject might not start exactly where it appears.
How do we wade through hissing or silence to tell consonants apart? Which cues do we grab onto to get us on top of these sound waves? In this episode, we take a look at obstruent acoustics: how they differ from vowels or other sonorous sounds, how the way we make fricatives influences the way they sound to us, and how we latch onto lightning-quick changes to tell us what stop we just heard.
How can we capture the meanings of transitive sentences? How do we match our syntax trees to our semantics?

What kinds of words are off-limits in different languages? How deeply does profanity affect us? In this episode, we talk about taboo language and euphemisms: how they work, when we're allowed to use what, how psychologically deep they go, and why we can't run on the same euphemisms forever.
How much meaning is there just in sounds? How much are words alike across languages? In this episode, we talk about the arbitrariness of the sign: how our sounds don't have to connect to the meanings they do, how much cases like onomatopoeia serve as a counter to the random matching of words, and whether individual sounds or syllables carry their own semantic punch.
How do we know what questions we can ask? What keeps us from moving words around into whatever order we want?

How do different languages play with pitch to create differences in meaning? How do we tell where stress falls?

How do we deal with gender when we process language? Do we take it into consideration when we hear words and sentences? In this week's episode, we talk about gender and language processing: the different kinds of gender in language, how gender influences our ability to retrieve words from our mental dictionaries, and how our views on gender temporarily keep us from considering otherwise legitimate interpretations of sentences.
How does a word know what role it should play in a sentence? How can we match up our verbs and nouns so that everything makes sense?

Where in the brain is language located, and how do we know? In this episode, we talk about neurolinguistics, the two main areas in the brain that are in charge of language, and two different neuroimaging techniques we use to look at where and when the brain does all its linguistic magic.
Why do people interpret the same sentence multiple ways? What is it about semantics that leads us to more than one meaning? We take on semantic scope, and talk about how the most innocent-seeming words in your sentence are fighting it out to bestow upon you an interpretation where they come out on top.
What are the parts of words that matter for meaning? They're not always as big as you might think. This week, we talk about morphemes, the smallest bits of meaning: how to find them, where to dig for them, and how different languages deal with them.
What happens when babies are exposed to more than one language at the same time? You might be worried about them getting confused, but we're here to talk about bilingualism, and how kids have no trouble working out how to build their two languages right.

When we deal with language, how do we know what sounds we hear match up to what categories? And how do we know what sounds to make ourselves? In the follow-up to our phoneme episode, we takes on allophones, the speech sounds that are driven by rules, and that define the way we hear our linguistic world.
With all the sounds we can make with our mouths, how do we know which ones are important for our language? We take a look at phonemes, the basic sounds of language, and how we can identify them, how we tell them apart, and how our brains react to them.
When we're studying language, which rules are the rules that matter? We take a look at prescriptive and descriptive rules, and explains why the rules that tell you how you actually do something are more interesting and more scientific than the ones that tell you how you should do it.
Our conversations may not always behave entirely logically, but we still have rules to follow. In this episode, we talk about the Cooperative Principle and the different Conversational Maxims that give us the rails our interactions run down.
