Explanation
Subject is a grammatical relation or function whose diagnosis depends on the language and theoretical framework. Agreement, position, case and syntactic behaviour can provide evidence but do not coincide everywhere. A subject is not universally the person performing an action: passive clauses and state descriptions may assign it other semantic roles. In the context of ergativity, grammatical functions cannot simply be read off case labels. With switch-reference, the relation actually tracked by the particular system must also be established. One school-grammar diagnostic from German cannot settle these comparisons.
Movement of thought
1. Identify the construction. 2. Apply several grammatical tests. 3. Record semantic roles separately. 4. Check the language-specific distribution. 5. Compare competing analyses.
Scientific use case
Cross-linguistic research can examine which subject properties cluster together or separate.
Example
In “The letter is being read”, the letter is the subject although it is not the reader.
Counterexample
The first noun phrase in a sentence need not be its subject in every language.
Distinction
Distinguish subject from agent, topic, nominative case and initial sentence position.
Effect on thought and perception
The concept separates grammatical organisation from event roles.
Resonance
The grammatical starting point need not be the actor.
