Study Notes – Tenses
CSIR NET – English Language
(MIT‑level, first‑principles treatment with rigorous reasoning, deeper theory, edge cases, and a challenging problem)
Prerequisite knowledge: Basic English morphology & syntax, introductory generative grammar, and a working knowledge of the four grammatical categories: tense, aspect, mood, and voice.
1. Introduction
- Tense is a grammatical category expressing when an event or state occurs relative to the moment of utterance.
- In English, tense is encoded morphologically, syntactically, and semantically.
- The study of tense is central to syntax‑semantics interface research: how the time of an event is represented in the sentence structure and interpreted by the hearer.
2. Theoretical Foundations
| Concept | What it Captures | Key References |
|---|---|---|
| Tense | Temporal position of an event relative to the speech time (ST). | Chomsky (1981, 2001); Jackendoff (1992) |
| Aspect | Temporal internal structure of an event (completed vs. ongoing). | Reuland (1998); Bresnan & Moro (1992) |
| Mood | Attitude or modal inference (indicative, subjunctive, imperative). | Carlson (2017) |
| Voice | Agentive vs. patientive orientation. | Halliday (1978) |
| TAM (Tense‑Aspect‑Mood) system | Composite feature bundle specifying the semantic time and modal/attitudinal content. | Biber (1999) |
2.1 Tense as a Feature
- Feature theory (Chomsky, 1995): Tense is a syntactic feature [T] that can be valued
-(past) or+(future). - Feature valuation: The feature checking mechanism ensures that the tense feature on T is eventually realized by an inflectional morpheme (e.g.,
-ed,-s,will).
2.2 Temporal Relations
- Speech Time (ST): Moment of speaking or writing.
- Event Time (ET): Time when the event actually occurs.
- Reference Time (RT): Time at which the event is anchored in the discourse.
- Temporal Precedence:
ST ⊇ RT ⊇ ET(in canonical order).
Tense choices affect how these times align. For instance:
| Tense | Typical Temporal Alignment |
|---|---|
| Past Simple | ET < RT < ST |
| Present Simple | ET = ST (habitual) |
| Future Simple | ST < RT ≤ ET |
3. Tense Categories (English)
| Category | Morphology | Example | Semantic Nuance |
|---|---|---|---|
| Simple | -s (pres.) / -ed (past) |
She walks. / She walked. | Single time reference |
| Progressive/Continuous | be + V‑ing |
She is walking. | Ongoing action at/around RT |
| Perfect | have + V‑past participle |
She has walked. | Completed action w/ relevance to RT |
| Perfect Progressive | have been + V‑ing |
She has been walking. | Ongoing action that has continued up to RT |
3.1 Future Constructions
| Form | Morphology | Example | Typical Use |
|---|---|---|---|
| Simple Future | will + base |
She will walk. | Predicted or decided future |
| Future Continuous | will be + V‑ing |
She will be walking. | Future ongoing state |
| Future Perfect | will have + V‑past participle |
She will have walked. | Future action completed before another future event |
| Future Perfect Continuous | will have been + V‑ing |
She will have been walking. | Future ongoing action completed by a future time |
| “Going‑to” Future |
