Cause and effect is one of the quiet engines of comprehension.
A passage tells us what happened, why it happened, what followed, and sometimes what might happen next. Strong readers notice those relationships even when they are not marked by an obvious word such as because.
For the central vocabulary bank, begin with the Primary 6 AL1 Advanced Top 100 Vocabulary List. This guide teaches the language used to trace causes, triggers, consequences and outcomes.
Cause Is Not Always the Same as Trigger
A cause helps produce an event. A trigger is often the immediate event that sets something in motion.
Weeks of frustration may be the underlying cause of an argument. One careless remark may be the trigger.
Useful Cause-and-Effect Vocabulary
| Word | Useful meaning |
|---|---|
| cause | something that helps produce an event |
| trigger | an immediate event that starts a reaction |
| factor | one of several influences |
| consequence | a result following from an action or condition |
| outcome | the final result of a process |
| impact | the effect something has |
| repercussion | a later or indirect consequence, often negative |
Signal Words
- because
- therefore
- as a result
- consequently
- since
- due to
- leading to
- resulting in
- so
These signals are helpful, but strong readers should also recognise cause and effect when no marker appears.
Chains of Consequence
Real passages often contain more than one step.
Heavy rain flooded the path. The event was delayed. Some participants left before the new start time was announced.
The first event causes the second, which contributes to the third. This is a causal chain.
Cause and Effect in Character Writing
Character development also follows causal structure.
- careless decision → damage;
- damage → guilt;
- guilt → admission;
- admission → consequence;
- consequence → reflection.
This structure helps Primary 6 students build stories that feel connected rather than episodic.
Cause and Effect in Comprehension
When a question asks why something happened, the answer should identify the relevant cause rather than merely repeat the event.
If a character left early because she believed the meeting had been cancelled, “she left early” is not the cause. The mistaken belief is.
Cause and Effect in Oral English
One reason food waste increases is that people sometimes buy more than they can consume. As a result, edible food may be discarded before it is used.
The vocabulary makes the reasoning easy to follow.
Common Mistakes
- confusing sequence with cause;
- assuming the first event caused the second merely because it happened earlier;
- ignoring multiple factors;
- using therefore when the conclusion does not follow;
- confusing consequence with punishment;
- stating an effect without identifying the cause.
Mini Diagnostic
- What is the difference between a cause and a trigger?
- What does consequently signal?
- Why is sequence not always causation?
- Give one example of a causal chain.
- What is a repercussion?
- Write one sentence using as a result accurately.
A Seven-Day Cause-and-Effect Routine
| Day | Action |
|---|---|
| 1 | Collect cause and effect signal words. |
| 2 | Separate causes, triggers and factors. |
| 3 | Build three-step causal chains. |
| 4 | Apply them to story events. |
| 5 | Find causal relationships in a passage. |
| 6 | Explain a real-world issue orally. |
| 7 | Retrieve the vocabulary from examples. |
For Parents and Teachers: Ask “What Made This Happen?”
Then ask whether there was one cause or several. That second question prevents overly simple reasoning.
The Real Goal: See the Relationship
Cause-and-effect vocabulary helps students organise events into explanations. It turns a list of happenings into a model of why things changed.
Return to the Primary 6 AL1 Advanced Vocabulary List. Choose five words connected to change, responsibility or consequence and build a causal chain around each.
Advanced Causality Lab: Chains, Factors and False Causes
Cause-and-effect language becomes more powerful when students learn that events can have several causes, one cause can create several effects, and events that happen in sequence are not automatically causally connected. This is where vocabulary starts supporting reasoning rather than merely linking sentences.
Cause, Trigger, Factor and Condition
| Word | Role | Example |
|---|---|---|
| cause | helps produce an outcome | prolonged rain causes flooding |
| trigger | starts an immediate reaction | one remark triggers an argument |
| factor | one influence among several | lack of sleep is one factor affecting concentration |
| condition | circumstance that allows or shapes an outcome | high humidity creates conditions favourable to mould |
Sequence Is Not Proof of Cause
If the school bell rings and it begins raining one minute later, the bell did not cause the rain. Strong readers distinguish “after this” from “because of this”. This simple habit becomes increasingly important in Science, news, argument and data interpretation.
Multiple Causes and Multiple Effects
Heavy rain + blocked drains + low-lying ground → flooding → transport delays + property damage + disrupted plans.
This model is more realistic than forcing every event into one cause and one effect. Vocabulary such as contributes to, increases the likelihood of, leads to, results in and is one factor in gives students more precise ways to express complex relationships.
Causal Confidence
- strong: causes, results in, leads directly to;
- moderate: contributes to, increases the chance of;
- cautious: may be associated with, may help explain.
Students should match the strength of the language to the strength of the evidence. This is useful far beyond English.
Cause-and-Effect Answer Frames
- The immediate cause was…
- One contributing factor was…
- This led to…
- As a consequence…
- The effect was worsened by…
- This may explain why…
Final Causality Challenge
Choose one everyday event—poor sleep, a delayed bus, food waste or a group-project disagreement. Build a causal map with at least three factors and three consequences. Then write one explanation using different levels of causal certainty rather than repeating because.
