Case marking is the grammatical system that shows what role a noun or pronoun has in a sentence, such as subject or object. In Intro to Semantics and Pragmatics, it connects form to meaning and thematic roles.
Case marking is how a language signals the grammatical or semantic role of a noun phrase, often by adding an ending, changing a pronoun form, or using a preposition. In Intro to Semantics and Pragmatics, it sits right where sentence form meets sentence meaning: you look at the surface shape of an argument and ask what part it is playing in the event.
A simple way to think about it is that case marking tells you who is doing what to whom. In languages with rich case systems, the subject of a verb might take one form and the object another, even if word order changes. That means the sentence can keep the same core meaning while the grammar still makes the roles clear.
This is why Latin and Russian come up so often in discussions of case. A noun can change form depending on whether it is functioning as a subject, direct object, indirect object, or showing another relation like possession or location. English has much less visible case on nouns, but pronouns still show it, as in I versus me, he versus him, and she versus her.
In this course, case marking is especially useful when you are studying thematic roles and case grammar. The grammatical label and the semantic role do not always line up perfectly, which is exactly where the analysis gets interesting. A subject is often an agent, but not always, and a passive sentence can switch the grammatical subject while keeping the same underlying event structure.
Case marking can also be expressed through prepositions instead of endings. That matters because the language still needs some way to show relationships among participants, even if it does not use inflection much. So when you see a phrase marked by a preposition, a case ending, or a special pronoun form, you are looking at the language’s way of mapping structure onto meaning.
Case marking is one of the cleanest places to see how semantics and syntax meet. It gives you a way to track how a language packages roles like agent, patient, and recipient, instead of assuming that meaning is only coming from word order.
That matters when you analyze why two sentences with the same words can feel different, or why a passive sentence still keeps the same event participants even though the subject changes. Case marking also helps explain why some languages can rearrange words more freely than English without losing clarity.
In this course, the term gives you a concrete tool for talking about grammatical relations versus thematic roles. That distinction comes up again and again when you compare surface structure to underlying meaning, especially in sentences where the syntax hides the semantic pattern. If you can spot case marking, you can usually trace who is linked to the verb and how that link is being shown.

Case marking often points you toward thematic roles, because the form on a noun phrase can show whether it is acting as an agent, patient, recipient, or another participant. The two are not identical, though. A case ending can tell you how a language structures the sentence, while thematic roles describe the meaning relationship between the verb and its arguments.
Grammatical relations
Case marking is one way languages signal grammatical relations like subject, object, and indirect object. That makes it a form-side clue for identifying how the sentence is built. In some languages, those relations are shown mainly by case endings, while in others word order does more of the work.
Syntactic structure
Case marking gives you evidence about syntactic structure because it shows how noun phrases are connected to the verb. If a sentence can be reordered without changing who is subject or object, the case system is carrying part of the structural load. That is useful when you compare surface order with deeper sentence organization.
Theta Assignment
Theta assignment is about how a verb assigns semantic roles to its arguments, and case marking can be one outward sign of that process. The case form does not create the role by itself, but it often makes the role visible in the sentence. That is why the two ideas are often studied together.
A quiz question might give you a sentence from a case-rich language and ask which noun is marked as the subject or object, or how the language shows role relationships without relying on fixed word order. You might also be asked to compare a case-marked language with English and explain why pronouns like I/me still preserve case distinctions. In short answer or discussion prompts, use case marking to trace how form points to meaning. If a sentence is passivized, show how the case pattern shifts even when the core event stays the same.
Case marking is the grammatical signaling of a noun phrase’s role in a sentence, often through endings, pronoun forms, or prepositions.
In semantics and pragmatics, case marking matters because it helps connect sentence form to participant roles in the event.
Languages with rich case systems can show subject, object, and indirect object relations even when word order changes.
English has limited case on nouns, but pronouns still preserve case distinctions like I versus me.
Case marking is easiest to see when you compare grammatical relations with thematic roles, since they overlap but are not always the same.
Case marking is how a language shows the role of a noun or pronoun in a sentence, such as subject, object, or indirect object. In this course, it matters because it links grammatical form to meaning and helps you trace thematic roles in a sentence.
Word order tells you a lot in languages like English, but case marking can do that job instead or alongside it. In a case-rich language, noun forms may show the role clearly even if the word order changes. That is why case systems often allow more flexible sentence structure.
English pronouns give easy examples: I changes to me, he to him, and she to her depending on sentence position. In languages like Latin and Russian, case marking can appear on nouns themselves, with different forms for subject, object, possession, or location.
Because case marking helps show who is doing what to whom. The case form can point you toward roles like agent or patient, while thematic roles explain the semantic relationship itself. Studying both makes it easier to analyze sentences where syntax and meaning do not line up in a simple way.
