Verb Tenses and Aspect: The Twelve-Tense System
Simple, continuous and perfect aspects across past, present, future and future-in-the-past; the present-perfect versus past-simple choice; time markers that force a tense; and the sequence-of-tenses habit for reported and complex sentences.
A Joy FM newsreader moves through tenses minute by minute: "Parliament PASSED (past) the bill last night; the unions HAVE WARNED (present perfect) that they WILL STRIKE (future) if the government DOES NOT REVIEW (present simple) the rates." One broadcast, four tenses, each with a time reason.
Key Syllabus Learning Objectives
- 1Build all twelve active tense forms for regular and irregular verbs
- 2Select tense from time markers (ago/for/since/already/now/next/by the time)
- 3Explain the present perfect versus past simple difference in context
- 4Recognise stative verbs that resist the continuous form
- 5Apply sequence of tenses in complex sentences with past reporting
The Construction Grid: Two Bricks, Four Mortars
- Irregular V2/V3 set WAEC prefers: go-went-gone, see-saw-seen, do-did-done, write-wrote-written, take-took-taken, come-came-come, run-ran-run.
- The auxiliary chain never skips: will (modal) + be + been — modals take the BARE form after them: *will goes is wrong.
- Past simple of be: was/were; subjunctive "were" survives in "If I were you" even for singular subjects.
- Aspect = completeness camera: simple = fact/habit, continuous = in progress, perfect = before-and-relevant.
A project poster at a Tamale NGO: "By 2030 we WILL HAVE BUILT forty boreholes" — future perfect: an action completed before a future deadline stated with BY.
Continuous = BE + -ing; perfect = HAVE + V3; tense = only the form of BE/HAVE/modal.
Present Perfect vs Past Simple: The Connection Test
- already (affirmative, before V) vs yet (negative/question, at end): "I have already eaten. Have you eaten yet?"
- just = very recent: "The headmaster has just left."
- "I have been to Kumasi" (visited, returned) vs "I have gone to Kumasi" (still there) — the gone/been pair is a WAEC classic.
- American simple-past with already ("I already ate") exists, but WAEC follows British convention: perfect.
A result-checking exchange at school: "Have you seen my WAEC slip?" (result now) — "I saw it on the table yesterday" (time specified, so past simple).
Definite past time = past simple; unfinished time or present result = present perfect.
Continuous, Habitual and Stative Verbs
- Habitual present simple: "The sun RISES in the east"; "Ama CATCHES the 6 a.m. tro-tro."
- Continuous for irritating habits with "always": "He is ALWAYS forgetting his ID card" (complaining tone).
- Future with present-continuous arrangement: "I am visiting my uncle on Saturday" (planned).
- Time clauses take present, not future: "When the bell RINGS (not will ring), leave." Same after as soon as, until, before, after, if.
A teacher's remark: "Kofi is always chatting, but he doesn't understand a word — is he knowing the answers to today's questions?" Both halves test stative verbs (know) and habit continuous.
State verbs stay out of -ing; time/condition clauses refuse will.
Past Perfect, Narrative Time and Sequence
- after / before / by the time + past event often trigger perfect: "By the time the ambulance came, the crowd had dispersed."
- no past perfect needed for automatic sequence with before/after ("After she ate, she left" is already clear) — WAEC rewards the had form when order is not signaled.
- the second continuous of the past: "had been waiting" emphasises duration before another past event: "They had been waiting 2 hours when the bus finally came."
- future-in-the-past (would) for old plans that unfolded or failed: "He promised he WOULD return."
A witness statement at a police station: "The shop had closed before the light went off; I was returning home when the alarm rang."
Two pasts, one earlier: give "had" to the earlier one.
- Scan for the SIGNAL WORD before choosing: ago/last/yesterday/in + past year = past simple; since/for/already/yet/ever/never/recently/so far/today(this week if unfinished) = present perfect.
- In objective items with two blanks describing past events, the EARLIER event almost always carries had + V3 — draw a tiny timeline on your paper.
- Future-in-the-past appears in essays as "would": "I would never forget that day" — use it for past habits/plans to lift expression marks.
- When asked to change a sentence to a given tense, keep everything else identical: examiners deduct for accidental verb changes beyond the required one.
- Stative verb list of 15 (know, believe, love, hate, want, need, own, possess, belong, contain, understand, remember, forget, seem, mean) covers nearly every continuous-error option in the objective paper.
- Putting a time word with present perfect: *"I have seen him yesterday" — yesterday is finished time, so past simple.
- Using "for" with a point date ("for 2020") or "since" with a span ("since five years").
- Continuous of stative verbs: "I am agreeing", "she is possessing a farm".
- Double future in time clauses: *"When I will arrive, call me" — the clause after when/until/if takes a present or past tense.
- Wrong past participle: "I have wrote", "he has drinked" — memorise V3 of the irregular high-frequency list.
- Sequence break: "The boy said he is tired" is fine for simultaneous truth, but WAEC expected backshift when the report itself is past and the feeling has ended: "he WAS tired."
- Can I build all twelve forms with "walk" and "go" without a table?
- Can I state the time-marker that forces each tense family?
- Can I choose have been to vs have gone to correctly?
- Can I list ten verbs that refuse the continuous form?
- Can I place past perfect in a two-event narrative sentence?
