Abstract.
This paper explores the semantic classification of actants and predicates in bivalent
syntactic structures, highlighting their roles in sentence meaning and construction. By analyzing
thematic roles such as Agent and Patient, Experiencer and Stimulus, Beneficiary and Recipient,
and Instrument and Theme, we examine how predicates determine valency and how actants fulfill
specific functions within event schemas. Through examples from both constructed sentences and
literary texts, this study demonstrates how actant-predicate relationships shape linguistic
expression. The findings have implications for syntax, semantics, discourse analysis, and
computational linguistics, offering insights into cross-linguistic variation and the cognitive
mechanisms underlying sentence processing.

The relationship between predicates and their actants lies at the core of linguistic analysis,
forming the foundation of sentence meaning and structure. Language serves as a means of
representing events, states, and processes, and this representation is largely shaped by the
interplay between the predicate—the element that expresses an action, event, or state—and its
actants, the entities participating in the situation described. Understanding how predicates and
actants interact is crucial for exploring the mechanisms by which meaning is constructed and
conveyed across different languages.
Semantic classification in linguistics seeks to categorize predicates and their actants based on their
functional roles in sentence structure. Predicates define the valency of a sentence, determining
how many and what kinds of actants are necessary to complete their meaning. Actants, on the
other hand, fulfill specific roles within the event schema, such as agent, patient, experiencer,
theme, recipient, and instrument. These roles are not arbitrary; they emerge from the intrinsic
meaning of predicates and are subject to cross-linguistic variation and typological constraints.
A thorough understanding of actant-predicate relations has significant implications for various
linguistic fields, including syntax, semantics, morphology, and discourse analysis. In syntactic
theory, the way actantsare encoded—through case marking, agreement, and word order—reflects
deep-seated principles of grammatical structure. In semantic theory, argument structure and event
semantics provide insight into how meaning is constructed and interpreted. The study of actants
and predicates is also crucial in applied domains such as computational linguistics, natural
language processing, language acquisition, and translation studies, where precise semantic
classification enhances machine understanding and linguistic modeling.
This section aims to explore the roles of actants and predicates from a semantic perspective,
highlighting major classification frameworks such as valency theory, theta theory, and frame
semantics. By examining the ways in which different linguistic models approach actant-predicate
relationships, we can gain a deeper understanding of how meaning is structured in language and
how these structures influence linguistic variation and processing.
Literary works provide numerous examples that illustrate these classifications in natural discourse,
demonstrating how meaning is constructed through actant-predicate relationships.

Agent and Patient
The most fundamental thematic roles in bivalent structures are Agent (the initiator of an action)
and Patient (the entity affected by the action). These roles are typical in transitive constructions
where the verb conveys an external action.
Example:
She closed the door.
Agent: She
Predicate: closed
Patient: the door
"He struck the match and watched it burn." (The Picture of Dorian Gray, Oscar Wilde)
Agent: He
Predicate: struck
Patient: the match
In both examples, the verb conveys an external, dynamic action where the Patient undergoes a
transformation. The thematic structure remains constant: an external initiator acts upon a passive
entity.
Experiencer and Stimulus
When the subject does not perform a deliberate action but instead undergoes an emotional,
sensory, or cognitive experience, it is termed an Experiencer. The entity causing the experience is
the Stimulus.
Example:
She feared the storm.
Experiencer: She
Predicate: feared
Stimulus: the storm
"Elizabeth admired Mr. Darcy’s generosity." (Pride and Prejudice, Jane Austen)
Experiencer: Elizabeth
Predicate: admired
Stimulus: Mr. Darcy’s generosity
Unlike Agent-Patient structures, Experiencer-Stimulus relationships involve perception, emotion,
or cognition rather than a direct external action. The subject does not act upon the object but
instead reacts to it, making the interaction more abstract.
Beneficiary and Recipient
Some bivalent structures include a Beneficiary, who benefits from the action, or a Recipient, who
receives something.
Example:
He gave his friend a book.
Agent: He
Predicate: gave
Recipient: his friend
Theme: a book
"Dumbledore handed Harry an envelope." (Harry Potter and the Sorcerer’s Stone, J.K. Rowling)
Agent: Dumbledore
Predicate: handed
Recipient: Harry
Theme: an envelope
These examples showcase a transactional relationship where a concrete object moves from one
party to another. The distinction between Beneficiary and Recipient depends on whether the act is

for someone's benefit (Beneficiary) or involves direct reception (Recipient). In these cases, the
second noun phrase (his friend / Harry) functions as the Recipient, not just a passive Patient.
Instrument and Theme
In some constructions, an Instrument is the means by which an action is performed, while the
Theme is the entity undergoing change or movement.
Example:
She cut the paper with scissors.
Agent: She
Predicate: cut
Theme: the paper
Instrument: scissors
"Gatsby lifted the glass with a trembling hand." (The Great Gatsby, F. Scott Fitzgerald)
Agent: Gatsby
Predicate: lifted
Theme: the glass
Instrument: a trembling hand
These structures introduce an additional element (Instrument) to highlight how the action occurs.
The use of an Instrument often implies an indirect action where the Agent utilizes an external tool
to achieve the desired effect.
The classification of actants and predicates reveals the intricate semantic relationships within
bivalent syntactic units. The interaction between thematic roles—such as Agent and Patient,
Experiencer and Stimulus, Beneficiary and Recipient, and Instrument and Theme—determines
how meaning is constructed in sentences. These roles help distinguish between different verb
types and their argument structures, enriching our understanding of sentence semantics.
Literary texts provide abundant examples of these relationships, demonstrating how authors use
bivalent structures to enhance narrative depth and expressiveness. The exploration of actant-
predicate relationships not only advances syntactic theory but also has implications for language
acquisition, discourse analysis, and natural language processing. Future research may investigate
how these semantic roles vary across different linguistic contexts and genres, further contributing
to our comprehension of language structure and meaning.
The study of semantic classification, particularly the roles of actants and predicates, is essential
for understanding the structure and meaning of sentences. The interaction between predicates and
their actants forms the foundation of linguistic representation, shaping how events, states, and
actions are conveyed across different languages. By examining bivalent syntactic units, we gain
insight into the ways thematic roles—such as Agent and Patient, Experiencer and Stimulus,
Beneficiary and Recipient, and Instrument and Theme—contribute to sentence meaning.
The classification of actants not only enriches syntactic and semantic theory but also holds
practical significance in applied fields such as computational linguistics, language acquisition,
translation studies, and discourse analysis. The presence of these relationships in literary texts
further highlights their role in shaping expressive and nuanced communication.
Future research could explore the cross-linguistic variations of these semantic roles, investigating
how different languages encode and interpret actant-predicate relationships. Such studies would
contribute to a deeper understanding of linguistic typology, cognitive processing, and the
evolution of meaning in human language.
