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.
How can we tell apart different sonorant consonants - your [n]s and [m]s, [l]s and [ɹ]s? What do their sound waves look like? 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?
