Transitivity describes whether and how a verb relates to participants in a Clause. In traditional grammar, it concerns whether a verb takes an object. In Functional Grammar (Halliday), transitivity is a far richer system for analysing how language represents experience.
| Pattern | Label | Example |
|---|---|---|
| Verb + no object | Intransitive | She slept. / The baby cried. |
| Verb + one object | Transitive | She read the book. |
| Verb + two objects | Ditransitive | She gave him a book. |
| Verb + object + complement | Complex transitive | They elected her president. |
Many English verbs can be both transitive and intransitive (She eats / She eats rice; The door opened / He opened the door), which is a source of L2 error when learners assume a verb is fixed in one pattern.
Ergative verbs deserve special attention: break, open, close, sink, melt. The same verb can appear with the affected entity as either object (He broke the vase) or subject (The vase broke). This is the ergative alternation, common in English but absent or different in many other languages.
In Systemic Functional Linguistics, transitivity is the system by which speakers represent their experience of the world. It analyses clauses in terms of three components:
This framework reveals meaningful choices. Describing a protest as "Police dispersed the crowd" (material process, police as Actor) versus "The crowd dispersed" (no Agent) encodes different representations of responsibility, a key insight for Discourse Analysis and critical literacy.
