What is Academic IELTS Writing Task 1 Graphs: Lexical Resources?
Lexical Resource is just a formal name for your vocabulary. You need the right words to explain what the graph shows.
What You Need
Words for Data
You need to describe numbers, amounts (like half or a quarter), and show when things change (go up or go down).
Important Rule
Keep It Simple & Correct
Do not try to remember long, difficult word lists. A simple word used correctly is much better than a difficult word used in the wrong way.
02 · Graph Types
Dynamic vs. Static Graphs
Before you write, you must ask: Does the graph change over time?
Graph Types
Dynamic Graphs (Change over time)
The graph shows time: days, months, or years (e.g., a line graph from 2000 to 2020).
Focus: Movement, trends, going up, going down.
Graph Types
Static Graphs (No time change)
The graph shows data at only one moment in time (e.g., a bar chart for the year 2023 only).
Focus: Comparing sizes, percentages, and categories.
Vocabulary by Graph Type
Different pictures need different words. Learn which words match which graph type.
Line Graph
Focus on time and movement
Words to use: rise, fall, increase, decrease, peak, level off, fluctuate.
- “In 2015, solar energy overtook coal energy.”
Bar Chart
Focus on comparison
Words to use: higher than, lower than, the highest, the lowest, similar to.
- “Spain ranked highest in holiday spending.”
Pie Chart
Focus on parts of a whole
Words to use: percentage, proportion, share, half, quarter, make up.
- “Gas accounted for 40% of the total.”
Table
Focus on numbers and ranking
Words to use: figure, amount, number, higher/lower than, approximately.
- “The table shows that Group A had the highest figure.”
03 · Data
Describing Exact Numbers
When a graph shows a clear number (like 25, 25%, or 25 million), use these simple nouns and verbs.
Type of Word
Word
Example Sentence
Verb
stand at
The figure for Spain stood at 25%.
Verb
reach
Sales reached 500 units in 2010.
Verb
was / were
The number of students was 30 million.
Noun
figure
The figure shows a large increase.
Noun
amount / number
The number of people grew quickly.
04 · Data
Approximate Numbers (Not Exact)
Sometimes the line on the graph is between two numbers. You do not know the exact number. Use these words to guess safely.
Very Close
Just over / Just under
Use these when the number is very close to a round number.
Example: 49% → “just under half”
Not Exact
About / Around
Use these when you are making a good guess.
Example: “Around 40% of students used the bus.”
Almost There
Nearly / Almost
Use these when the number is very close to the top.
Example: “Nearly 75% of energy came from gas.”
05 · Variety
Fractions and Percentages
Do not write “%” in every sentence! If you want a good score, change percentages into words.
50%
Half
Or write “one in two”.
33%
A third
Or write “one in three”.
25%
A quarter
Or write “one in four”.
75%
Three quarters
Very useful for large amounts.
Useful Verbs for Percentages: Instead of writing “50% of people chose tea”, you can use verbs like account for or make up.
Example: “Tea accounted for half of the total drinks.”
06 · Trends
Going Up
For dynamic graphs, you need words that show the line moving higher.
Action Words (Verbs)
How to say "Go Up"
- Normal: increase, rise, grow, climb, go up.
- Strong (very fast): soar, rocket, surge.
- Example: Sales increased from 100 to 500 in 2010.
Naming Words (Nouns)
How to say "An Up"
- Nouns: an increase, a rise, a growth, an upward trend.
- Example: There was a sharp rise in sales in 2010.
- Tip: Learn the pairs: rise (verb) → a rise (noun).
07 · Trends
Going Down
You also need words to show when the numbers get smaller or the line goes lower.
Action Words (Verbs)
How to say "Go Down"
- Normal: decrease, fall, drop, decline, go down.
- Strong (very fast): plunge, plummet.
- Example: Car production fell to 50 units.
Naming Words (Nouns)
How to say "A Down"
- Nouns: a decrease, a fall, a drop, a decline, a downward trend.
- Example: The graph shows a gradual decline in oil use.
- Tip: Learn opposite pairs: increase ↔ decrease.
08 · Details
How Big Was the Change?
To get a higher score, you must tell the examiner how the number changed. Was it a big change or a small change?
Size of Change
Adjective + Noun (A ... change)
Verb + Adverb (Changed ...)
Big and fast
a dramatic rise
rose dramatically
Big
Big
increased significantly
Medium
a moderate growth
grew moderately
Small
a slight drop
dropped slightly
Slow and steady
a gradual fall
fell gradually
Important Rule: Do not use the word “sharply” for a very small change! Only use it for big, fast changes.
09 · Movement
Fluctuation, Stable Data, and Peaks
Graphs do not always go in straight lines. Learn how to describe other types of movement.
Up and Down
Fluctuate
When a number goes up and down many times.
“Prices fluctuated between $10 and $20.”
No Change
Remain Stable
When the number stays the same over time.
“The figure remained stable at 50%.”
Highest Point
Peak at
When the line reaches the very top.
“The figure peaked at 75% in 2015.”
Lowest Point
Hit a low
When the line reaches the very bottom.
“The figure fell to a low of 20%.”
10 · Comparison
Comparing Information
You must compare the different lines or bars on the graph. Use these simple comparison words.
More
Higher / Greater
• higher than
• greater than
• more than
“France was higher than Italy.”
Less
Lower / Fewer
• lower than
• less than
• fewer than (for things you count)
“Sales were lower than in May.”
Same
Similar To
• the same as
• equal to
• similar to
“The two figures were similar.”
Want a higher score? Add a size word!
Instead of saying “higher than”, say “slightly higher than” (small difference) or “considerably higher than” (large difference).
11 · Static Graphs
Vocabulary for Static Graphs
If there is NO time change (no years, no months), do not use words like “increase” or “decrease”.
What to focus on in Static Graphs
No Time Change
In a static graph, you must focus on comparing the categories. Who is number 1? Who is last?
- Use the highest figure or the lowest figure.
- Use the largest proportion or the smallest proportion.
- Use the most popular or the least popular.
Example: “Cycling was the most popular activity, while swimming had the lowest figure.”
12 · Grammar for Vocab
Small Words: Prepositions
Using the correct preposition (at, to, by, of) is very important for an accurate score.
Preposition
When to use it
Example Sentence
At
a specific point or starting level
Sales stood at 500.
to
the end point
It increased to 800.
by
the amount of change
It rose by 300. (from 500 to 800)
of
giving a value or peak
It reached a peak of 1,000.
between ... and
a range
It fluctuated between $10 and $20.
13 · Watch Out
Common Mistakes to Avoid
Many students make these same mistakes. Look at the wrong sentences and the correct sentences.
✕ Wrong English
- 1. There was a sharp rose.
- 2. Prices went up like crazy.
- 3. The number increased in 50%.
- 4. A peak in 1,000.
✓ Correct IELTS English
- There was a sharp rise. / It rose sharply. (Noun vs Verb)
- Prices increased significantly. (Formal language)
- The number increased by 50%. (Correct preposition)
- A peak of 1,000. (Correct preposition)
14 · Final Plan
Key Takeaways: 4 Steps to Success
Remember these four simple steps when you write your Task 1 essay.
Your Action Plan
- Step 1: Identify the graph. Is it dynamic (showing time) or static (no time)?
- Step 2: Vary your words. Mix “verb + adverb” (increased significantly) with “adjective + noun” (a significant increase).
- Step 3: Replace percentages. Do not write % all the time. Use fractions (a quarter) and verbs (account for).
- Step 4: Check your prepositions. Always check if you wrote at, to, by, or of correctly.
Final Tip
Clear + accurate + varied vocabulary = a stronger Lexical Resource score.
A simple correct word is always better than a difficult wrong word!
15 Common questions
Academic IELTS Writing Task 1 Graphs: Frequently asked questions
Quick answers to what candidates ask most about Academic IELTS Writing Task 1 Graphs: Lexical Resources
What vocabulary should I use for IELTS Academic Writing Task 1 graphs?
Use a range of vocabulary for trends, changes, comparisons, figures and proportions. Useful verbs include increase, rise, grow, fall, decline, fluctuate and remain stable. Adverbs such as slightly, gradually, steadily, significantly and dramatically can help you describe the degree of change accurately.
How can I improve my lexical resource in IELTS Writing Task 1?
Learn vocabulary in functional groups rather than memorising isolated words. Practise language for increases, decreases, stability, fluctuations, comparisons, percentages and approximate figures. You should also learn different ways to express the same idea without repeating the same words.
What are useful words for describing increases and decreases in graphs?
For increases, you can use rise, increase, grow, climb, surge and jump. For decreases, useful alternatives include fall, decrease, decline, drop, dip and plunge. Choose vocabulary according to the size and speed of the change so that your description remains accurate.
How can I avoid repeating the same vocabulary in IELTS Task 1?
Build a range of synonyms and related expressions, but do not replace words simply for the sake of variety. For example, you can use increased, rose and grew when appropriate, while varying sentence structures as well as vocabulary. Accuracy and natural usage are more important than using unusual words.
What vocabulary can help me achieve a higher band in IELTS Writing Task 1?
Higher-band responses use precise, varied and appropriate vocabulary rather than simply using difficult words. Learn expressions for describing the degree of change, making comparisons, reporting figures and identifying significant trends. Using this language accurately and naturally can help demonstrate a stronger Lexical Resource.
