1. Introduction: Why Tenses Matter
| What | Why it matters |
|---|---|
| Tense | Marks the time of an event or state relative to the utterance. |
| Aspect | Adds information about the internal temporal structure (e.g., completion, duration). |
| Mood | Expresses modality (necessity, possibility, permission). |
Key Insight – In English, tense is a syntactic property of the clause (
T‑head) that is realized morphologically (verb inflection, auxiliaries).
2. First Principles of Tense
-
Semantic Core – A verb denotes an event or state (
V) that occurs at a time point (t). -
Temporal Reference – The clause’s
T‑head selects a temporal variable (τ) and assigns it tot. -
Syntactic Realization – The
T‑head is realized by:- Morphology (past‑tense ‑ed, present‑tense ‑s).
- Auxiliaries (
be,have,will, etc.) combined with the base form.
-
Tense–Aspect–Mood (TAM) Interface –
T(tense) chooses a time (past, present, future).V(verb) can be modified by aspectual prefixes/suffixes or auxiliary chains.Moodis encoded by modal auxiliaries or periphrastic constructions.
-
Time‑Reference vs. Temporal Formula –
- Time‑Reference: Where the event occurs relative to
τ. - Temporal Formula: The order of events (sequence, overlap, interruption).
- Time‑Reference: Where the event occurs relative to
3. The Three Main Tense Categories
| Category | Example | Semantics |
|---|---|---|
| Past | She walked. | Event occurred before utterance. |
| Present | She walks. | Event coincides with utterance. |
| Future | She will walk. | Event after utterance. |
3.1 Simple Tenses
| Tense | Morphology | Example | Usage |
|---|---|---|---|
| Present Simple | V + s/es (3rd‑person) |
The river flows. | Habitual, general truths. |
| Past Simple | V + ‑ed (regular) |

| Future Simple | will + V |
It will rain tomorrow. | Predictions, promises. |
3.2 Continuous / Progressive Tenses
| Tense | Structure | Example | Notes |
|---|---|---|---|
| Present Continuous | am/is/are + V‑ing |
She is studying. | Ongoing action. |
| Past Continuous | was/were + V‑ing |
They were hiking. | Interrupted action. |
| Future Continuous | will be + V‑ing |
We will be camping. | Future ongoing action. |
3.3 Perfect Tenses
