Narrative Expressions: Once Upon a Time, All of a Sudden, The Moral of the Story

What this session covers

Stories are everywhere in English — fairy tales, news reports, personal experiences, business case studies, films. English has many fixed expressions for telling stories. 'Once upon a time' (story opening — fairy tales). 'All of a sudden' (sudden event). 'The next thing I knew' (sudden change). 'To cut a long story short' (skip details). 'In the end' (final outcome). 'The moral of the story' (lesson learned). 'As it turned out' (the truth was revealed). 'To make matters worse' (problem became bigger). Each fits a different part of a narrative. Students who tell stories without these chunks sound flat — they cannot signal openings, transitions, conclusions. The lesson uses simple language so all teachers can follow. Connects to time and frequency expressions (#68), discourse markers (#30), and emphasis expressions (#74). Together these cover the main fixed-expression areas of advanced English.

Personal Reflection

Before you start — think honestly about your own teaching and experience.

Q1
When your students tell personal stories or recount events, do they sound flat — moving from one fact to another without the natural transitions and signals that English narrative uses? Do they know expressions like 'all of a sudden' or 'in the end'?
Q2
Which of these have you seen your students get wrong or avoid using altogether?

Discover the Pattern

Look at the examples. Answer each question before reading the explanation — this is how your students will learn too.

1
Opening expressions:

For fairy tales and made-up stories:
Once upon a time, there was a brave girl who lived in a small village.
Long, long ago, in a faraway land...

For real stories:
When I was younger, I had a strange experience.
Let me tell you about something that happened last year.
It all started when I was seven years old.
Something extraordinary happened to me last week.

Why do stories need specific openings?

Stories need clear openings to signal that a narrative is starting and to set the scene. 'Once upon a time' is the classic fairy-tale opener — the listener immediately knows it is a made-up story. 'Long, long ago' is similar but less specifically a fairy tale. For real stories, the openings are different — they often establish time and personal context. 'When I was younger' (a memory). 'Let me tell you about' (signalling a story is coming). 'It all started when' (the beginning of a sequence). 'Something extraordinary happened' (signalling significance). Each opening tells the listener what kind of story is coming. Without an opening, the speaker just starts talking without preparing the listener — the result feels abrupt and confusing.

2
Middle expressions — for events and changes:

For sudden events:
All of a sudden, the lights went out.
Out of the blue, my old friend called.
Without warning, the storm started.

For sudden changes:
The next thing I knew, we were on the wrong train.
Before I knew it, three hours had passed.
Suddenly, everything changed.

For things getting worse:
To make matters worse, it started to rain.
As if that were not bad enough, my phone died.
On top of that, we got lost.

For revealing truth:
As it turned out, the man was actually a famous actor.
It later emerged that the rumour was false.
We learned that everything had been a misunderstanding.

Why do stories need so many transition expressions?

Stories move through events and changes. Transitions help the listener follow. 'All of a sudden' signals a sudden event — the listener knows something unexpected is coming. 'The next thing I knew' signals a sudden change of state — usually the speaker did not see it coming. 'To make matters worse' signals that things are getting worse — the listener prepares for more bad news. 'As it turned out' signals revelation — the truth was different from what was thought. Each transition prepares the listener for what is coming and structures the story. Without these chunks, stories feel flat — events come without warning or context. Native speakers use these constantly when telling stories. Mastering 8 to 10 transition expressions transforms storytelling.

3
Closing expressions:

For outcomes:
In the end, everything worked out fine.
Finally, after months of waiting, the news arrived.
Eventually, the situation improved.

For summarising:
To cut a long story short, we missed the bus and had to walk home.
In short, the trip was a disaster.
Long story short, we never found the lost dog.

For lessons:
The moral of the story is — always check your bag before leaving.
What I learned from that experience was — patience pays off.
It taught me an important lesson.

For wrapping up:
And that is how I met your mother.
And they all lived happily ever after.
And that is the story.

Why do stories need clear endings?

Stories need clear endings so the listener knows the story is over. 'In the end' signals the final outcome — what happened ultimately. 'Finally' is similar but emphasises the long wait or process. 'To cut a long story short' acknowledges that the speaker is skipping detail to get to the conclusion — useful for listeners who need the main point. 'The moral of the story' explicitly states the lesson — common in fables and stories with a teaching purpose. 'And they all lived happily ever after' is the classic fairy-tale ending. 'And that is the story' is a casual everyday ending. Without an ending, the story can feel unfinished — the listener does not know if more is coming. Clear endings give stories shape.

The Pattern — What You Just Discovered

English has many fixed expressions for storytelling. Openings: once upon a time (fairy tales), let me tell you about, it all started when. Middle (events): all of a sudden, the next thing I knew, to make matters worse, as it turned out. Closings: in the end, finally, to cut a long story short, the moral of the story. Each fits a different part of a narrative. Students who use these chunks tell stories naturally and structure narratives clearly.
Expression Function Type of story Example
Once upon a time Story opening Fairy tales, made-up stories Once upon a time, there was a brave princess.
It all started when Story opening Real personal stories It all started when I was seven years old.
Let me tell you about Story opening — invitation Personal stories Let me tell you about my first day at school.
All of a sudden Sudden event Any narrative All of a sudden, the lights went out.
The next thing I knew Sudden change of state Personal stories The next thing I knew, we were on the wrong train.
To make matters worse Things get worse Stories with problems To make matters worse, it started to rain.
As it turned out Revelation — truth revealed Mystery or surprise As it turned out, he was actually a famous actor.
In the end Final outcome Any narrative In the end, everything worked out fine.
To cut a long story short Skip details, summarise Long stories To cut a long story short, we missed the bus.
The moral of the story Lesson learned Stories with teaching purpose The moral of the story is — always plan ahead.
They all lived happily ever after Fairy tale ending Fairy tales And they all lived happily ever after.
And that is the story Casual ending Personal stories And that is the story of how I met your mother.
Usage Notes

NOTE 1 — Match expressions to story type: Fairy tales use 'once upon a time' and 'they all lived happily ever after'. Real stories use 'it all started when' and 'and that is the story'. Don't mix the styles — using 'once upon a time' for a personal story sounds odd unless you are being playful.

NOTE 2 — Use transitions between events: Stories without transitions feel flat. Add 'all of a sudden' for sudden events. Add 'to make matters worse' when things go wrong. Add 'as it turned out' when truth is revealed. Each transition prepares the listener.

NOTE 3 — Signal endings clearly: 'In the end' marks the final outcome. 'To cut a long story short' summarises. 'The moral of the story' states a lesson. Without clear endings, stories feel unfinished. Pick the right ending for your story type.

NOTE 4 — These are fixed chunks: 'Once upon a TIME' (with 'a'). 'All OF A sudden' (full phrase). 'In THE end' (with 'the'). 'The MORAL of the story' (with 'the'). The exact wording must be used — changing words breaks the expression.

NOTE 5 — Avoid stacking too many: Using too many narrative expressions in one story sounds clichéd. One opening, two or three transitions, one ending is plenty. Plain language between the chunks lets each expression have impact.

Note

Narrative expressions are essential for any story telling — personal stories, news reports, case studies, fiction. Students who use these chunks tell stories naturally and confidently. Students who do not often sound flat — moving from one fact to another without signals or transitions. The lesson connects to time expressions (#68), discourse markers (#30), and emphasis expressions (#74). Together they cover the main fixed-expression areas of advanced English communication. Cultural context: storytelling is universal but the specific English chunks are particular. Students should learn the chunks even when they translate similar ideas from their first language.

💡

Practise narrative through story telling. One student tells a short story about a real or imagined event. They must use at least three narrative expressions — opening, transition, ending. The class checks for natural use. Drill the chunks until they come automatically when telling stories.

Common Student Errors

Once upon the time, there was a brave young king who lived in a faraway land.
Once upon a time, there was a brave young king who lived in a faraway land.

Pick the most appropriate word:
You are telling a story about a normal day that suddenly turned dramatic — the lights went out unexpectedly.
Pick the most appropriate word:
You are explaining a story but the listener has limited time. You want to skip details and get to the main outcome.
Pick the most appropriate word:
You are ending a fable about a fox and a crow. You want to state the lesson the story teaches.
Pick the most appropriate word:

Check Your Understanding — Part 2: Why Is It Wrong?

Each sentence has a problem with a narrative expression. Suggest a better version and explain.

Once upon the time, there was a poor woodcutter who lived alone in the forest.
Write the correct sentence:
Explain why it is wrong:
Once upon a time, there was a poor woodcutter who lived alone in the forest.
The fixed phrase is 'once upon A time' (with 'a', not 'the'). The article 'a' is essential. 'Once upon the time' is wrong. Always 'once upon a time' for the classic fairy-tale opening.
All sudden, my phone started ringing in the middle of the meeting.
Write the correct sentence:
Explain why it is wrong:
All of a sudden, my phone started ringing in the middle of the meeting.
The fixed phrase is 'ALL OF A sudden'. 'All sudden' drops 'of a' and is incomplete. The full phrase must be used. 'Suddenly' is also a valid word but the fixed chunk for stories is 'all of a sudden'.
In end, we made it home safely after a long and difficult journey.
Write the correct sentence:
Explain why it is wrong:
In the end, we made it home safely after a long and difficult journey.
The fixed phrase is 'IN THE end' — with 'the'. 'In end' drops 'the' and is incomplete. The article 'the' is essential. Always 'in the end' for the final outcome of a story.
The moral the story is to never trust strangers in dark forests.
Write the correct sentence:
Explain why it is wrong:
The moral of the story is to never trust strangers in dark forests.
The fixed phrase is 'the moral OF the story' — the word 'of' is essential. 'The moral the story' drops 'of' and is incomplete. Always 'the moral of the story is' for stating the lesson.

Classroom Teaching Sequence

Use this sequence directly in class — guided discovery, no textbook needed. Tap each step to mark it done.

0 / 5 done
1

STEP 1 — Stories need structure (5 min): Discuss with the class. Stories have openings, middles, and endings. English uses fixed expressions to signal each part. Establish that this lesson teaches the chunks for natural storytelling.

2

STEP 2 — Openings (6 min): Drill the openings. Once upon a time (fairy tales). Let me tell you about (real stories). It all started when (chronological start). When I was younger (memory). Match each to a story type. Practise five examples.

3

STEP 3 — Middle transitions (8 min): Drill the transitions. All of a sudden (sudden event). The next thing I knew (sudden change). To make matters worse (problem worsens). As it turned out (revelation). On top of that (additional problem). Practise five examples.

4

STEP 4 — Endings (8 min): Drill the endings. In the end (final outcome). To cut a long story short (summary). The moral of the story (lesson). Eventually (after long time). And that is the story (casual ending). Match each to a story type.

5

STEP 5 — Tell a story (8 min): Each student tells a short story (real or imagined) using at least one opening, two transitions, and one ending. The class checks for natural use of the chunks. Discuss which expressions worked best.

1 Narrative expressions wall (display)
Create a wall display organised by part of story: OPENINGS, TRANSITIONS (events), TRANSITIONS (problems), TRANSITIONS (revelations), ENDINGS. Refer to the wall when students tell stories.
Example sentences
OPENINGS: once upon a time (fairy tale), let me tell you about, it all started when, when I was younger, something extraordinary happened
EVENTS: all of a sudden, the next thing I knew, suddenly
PROBLEMS: to make matters worse, on top of that, as if that were not bad enough
REVELATIONS: as it turned out, it later emerged that, we found out that
ENDINGS: in the end, finally, eventually, to cut a long story short, the moral of the story, and that is the story
2 Match expression to story part (oral drill)
Describe a part of a story. Students must produce the right expression. The exercise drills automatic association of story part with expression.
Example sentences
Teacher: 'starting a fairy tale' → Student: 'once upon a time'
Teacher: 'a sudden event in story' → Student: 'all of a sudden'
Teacher: 'problem getting worse' → Student: 'to make matters worse'
Teacher: 'truth revealed' → Student: 'as it turned out'
Teacher: 'final outcome' → Student: 'in the end'
Teacher: 'stating the lesson' → Student: 'the moral of the story is'
3 Tell a complete story (speaking)
Each student tells a short story (real or imagined) using at least four narrative expressions across opening, middle, and ending. The class checks for natural use and story structure.
Example sentences
Sample story: 'Let me tell you about something that happened to me last month. It all started when I missed my morning bus. I decided to walk to work. Halfway there, all of a sudden, it started to rain. To make matters worse, my umbrella was at home. I ran for shelter under a shop awning. As it turned out, the shop owner recognised me from the village and offered me tea. We talked for an hour about old times. In the end, the rain stopped and I was only a little late for work. The moral of the story is — even bad situations can lead to good things.'

Plan Your Next Steps

For each strategy, choose the option that best describes where you are now.

Build the narrative vocabulary further with related expressions: meanwhile (at the same time), in due course (eventually formal), to my surprise (revelation), little did I know (foreshadowing), as fate would have it (revelation with fate), in retrospect (looking back).
Connect to time expressions (#68), discourse markers (#30), emphasis expressions (#74). Together they cover the main fixed-expression areas of advanced English communication.
Look at how narrative expressions appear in news, documentaries, and films. Real-world examples reinforce the chunks and show natural use. The expressions are everywhere in story-based content.
Teach related skills — stories often have characters, settings, conflicts, resolutions. The narrative expressions help structure these elements. Together with describing words from other lessons, students can build complete stories.
Ask students to write a short personal story using at least five narrative expressions. The exercise drills the chunks in real personal context.
What is the one change you will make next time you teach this vocabulary?

Key Takeaways

1 English has many fixed expressions for storytelling. Openings: once upon a time (fairy tales), let me tell you about (personal stories), it all started when (chronological). Middles: all of a sudden (sudden event), the next thing I knew (sudden change), to make matters worse (problems worsen), as it turned out (revelation). Endings: in the end (outcome), to cut a long story short (summary), the moral of the story (lesson).
2 Match expressions to story type. Fairy tales: once upon a time, they all lived happily ever after. Personal stories: it all started when, and that is the story. News stories: have specific journalistic conventions. Each story type has its own typical chunks.
3 These are fixed phrases. 'Once upon A time' (with 'a'). 'All OF A sudden' (full phrase). 'In THE end' (with 'the'). 'The moral OF the story' (with 'of'). Drop or change words and the expressions break.
4 Use transitions between events. Stories without transitions feel flat. 'All of a sudden' prepares the listener for surprise. 'To make matters worse' prepares for more bad news. 'As it turned out' prepares for revelation. Each transition gives the story shape.
5 Avoid stacking too many. One opening, two or three transitions, one ending is plenty for a short story. Stacking too many sounds clichéd. Plain language between the chunks lets each expression have impact.
