IELTS Map Description: The Language Most People Miss

Map tasks and process diagrams are the two question types where IELTS candidates lose the most marks unnecessarily. Most students can name a few locations and mention basic changes, but that is Band 5-6 language — and examiners know the difference immediately. The precise location phrases, change vocabulary, and sequencing connectors that separate a Band 7 from a Band 6 are surprisingly learnable, yet most candidates never study them. This guide gives you every expression you need for both question types, with examples you can start using in your next practice essay.

Part 1: How to Describe a Map in IELTS

Map tasks typically show either a single map with proposed changes, or two maps of the same location at different points in time (a before-and-after comparison). Your job is not to describe everything you see — it is to select and organise the most significant features and changes, and report them clearly using appropriate academic language.

Understanding What the Map Is Asking

Before you write a single word, spend 2–3 minutes analysing the map carefully. Ask yourself:

• What has changed between the two time periods, or what is proposed?
• What has stayed the same?
• Are changes concentrated in one area, or spread across the whole location?
• What is the overall trend — development, demolition, expansion, conversion?

Identifying the overall trend is essential because your overview paragraph must summarise the map at a high level, just as you would summarise a trend in a line graph. Examiners expect an overview that goes beyond listing individual features.

Location Language for Map Tasks

Precise location language is one of the clearest differentiators between a Band 6 and a Band 7 response. Avoid vague phrases like “on the left” or “at the top.” Instead, use the compass-based and spatial language that appears in academic writing.

Compass directions:

• To the north / south / east / west of the town centre lies a residential area.
• In the northern part of the site, a car park has been added.
• Along the southern boundary, the road has been widened.

Relative position:

• Adjacent to the library, a new car park has been built.
• Opposite the school, a supermarket now stands where houses once were.
• Immediately to the left of the main entrance is a reception area.
• Directly behind the factory, a storage facility has been constructed.

Central and peripheral locations:

• In the centre of the development, a communal garden has been introduced.
• At the heart of the complex sits a large conference hall.
• On the outskirts of the town, farmland has been converted into housing estates.
• At the eastern edge of the site, the river remains unchanged.

Proportional and area language:

• The northern half of the building has been redesigned as open-plan office space.
• A small section of the car park has been replaced by a cycle lane.
• The majority of the western area has been cleared to make way for the new road.

Change Language for Before-and-After Maps

When describing changes between two time periods, you need a variety of structures to avoid repetition. Aim to use at least four or five distinct change expressions across your response.

Replacement:

• The old factory was replaced by a supermarket.
• The open field has been replaced with a sports complex.
• In place of the car park, a pedestrian plaza now exists.

Demolition:

• The residential houses were demolished to make way for the new road.
• Several buildings were knocked down to allow for the expansion of the leisure centre.

Construction:

• A new bypass was constructed to the south of the town.
• A footbridge has been built across the river, connecting the two halves of the park.
• Two new blocks of flats were erected on the eastern side of the development.

Conversion:

• The farmland has been converted into a business park.
• The old warehouse was transformed into a community arts centre.
• The school building has been repurposed as a medical clinic.

Retention (no change):

• The church, which remains unchanged, continues to occupy the central position.
• Unlike the surrounding area, the woodland to the north has been preserved.
• The main road has retained its original route despite the surrounding redevelopment.

Relocation:

• The bus station was relocated from the town centre to the northern edge of the settlement.
• The car park has been moved further from the main entrance.

What to Include and What to Omit

A common mistake is trying to describe every single feature on the map. This leads to a list-like response with no grouping or overview — exactly what examiners penalise under Coherence and Cohesion.

Include:

• All major changes (construction, demolition, conversion)
• Significant features that remain the same, especially if they anchor the reader’s understanding of the layout
• The overall direction of change (e.g., the town has expanded significantly to the west)

Omit or briefly mention:

• Minor details that do not contribute to the main story (e.g., a small path that has been slightly rerouted)
• Features that are identical in both maps and do not help contrast change with stability

Group related changes together. For example, if three buildings in the western sector have all been demolished and replaced, describe those together in one paragraph rather than mentioning each one separately across your response.

Sample Overview for a Map Task

Overall, the most significant transformation has been the large-scale expansion of the town to the north and east, with agricultural land giving way to residential and commercial development. The town centre, by contrast, has seen relatively little structural change.

Notice that this overview does not mention specific buildings or roads — it captures the big picture in two sentences.

Part 2: IELTS Task 1 Process Diagram Connectors

Process diagrams require a completely different skill set from maps. Rather than describing location and change, you are describing a sequence of stages — how something is made, how it works, or how a natural cycle operates. The two most important features of a high-scoring process diagram response are accurate sequencing language and consistent use of the passive voice.

For a broader look at the vocabulary needed across different Task 1 question types, including how to describe trends in bar charts and line graphs, see our guide on essential Task 1 vocabulary for trends and bar charts.

Linear vs. Cyclical Processes

Before choosing your language, identify which type of process you are dealing with.

Linear processes have a clear beginning and end — for example, the manufacturing of a product, or the stages of water treatment. They move from Stage 1 to a final stage.

Cyclical processes have no fixed start or end point — for example, the water cycle, the life cycle of a butterfly, or the carbon cycle. In a cyclical process, the final stage leads back to the beginning.

This distinction matters because cyclical processes require you to choose a starting point and then make clear that the process loops back. You might write:

The cycle begins with evaporation from the ocean’s surface, and ultimately returns to this stage once precipitation has fallen and run off into the sea once more.

Sequencing Language for Linear Processes

Strong IELTS Task 1 process diagram connectors do more than just list steps in order. They show logical relationships between stages — causation, condition, immediacy, and completion.

Opening the process:

• First / Firstly, raw materials are fed into the machine at the intake valve.
• The process begins when timber is harvested from managed forests.
• At the initial stage, the ore is extracted from the mine.
• The first step involves crushing the raw material into a fine powder.

Moving between stages:

• Subsequently, the mixture is transferred to a holding tank where it is heated to 80°C.
• Following this, the liquid is filtered to remove any remaining impurities.
• After this stage has been completed, the product moves along a conveyor belt to the packaging unit.
• Once the water has been purified, it is pumped into the distribution network.
• The next stage involves cooling the substance rapidly to prevent crystallisation.
• At this point, the semi-processed material is divided into equal portions.
• This is then followed by a quality control inspection.
• Immediately after, the bottles are sealed and labelled.

Showing cause or condition:

• As a result of the heating process, the solids dissolve completely.
• This causes the gas to expand and rise to the surface.
• When the temperature reaches 100°C, the liquid begins to evaporate.
• Provided that the mixture reaches the correct consistency, it proceeds to the moulding stage.

Closing a linear process:

• Finally, the finished goods are packaged and dispatched to retailers.
• The process concludes with a safety inspection before the product is released for sale.
• At the final stage, the treated water is discharged back into the river.
• The last step in the process is the application of a protective coating.

Passive Voice in Process Diagrams

In a process diagram, the passive voice is almost always the correct choice. This is because process diagrams typically describe what happens to a material or substance — the agent (the person or machine performing the action) is either unknown, unimportant, or already implied by the diagram.

Incorrect (unnecessarily active):

Workers crush the ore and then they heat it in a furnace.

Correct (passive, academic):

The ore is crushed and heated in a furnace.

Key passive structures to practise:

• is / are + past participle (present simple passive) — for timeless or general processes
• is / are then + past participle — to show sequence
• is / are subsequently + past participle — more formal sequencing
• has been + past participle — occasionally used when describing completed stages in a manufacturing context

Example sequence using passive voice throughout:

First, the timber is harvested and transported to the processing plant. It is then cut into planks of uniform thickness before being dried in a kiln for 48 hours. Once the drying process has been completed, the planks are treated with a preservative chemical and subsequently stored in a ventilated warehouse until they are ready for distribution.

Notice how the passive voice keeps the focus on the material (timber) rather than on any agent, which is exactly what is expected in a formal academic description of a process.

Describing a Cyclical Process

For a cyclical process, you need to signal that the sequence has no definitive end. Useful phrases include:

• …and the cycle begins again.
• …returning to the initial stage.
• This completes the cycle, which then repeats.
• …before the process recommences from the beginning.
• The final stage feeds back into the first, as…

Example overview for a cyclical process:

Overall, the diagram illustrates a continuous cycle involving four distinct stages, beginning with evaporation and ending with the runoff that returns water to the ocean, at which point the process repeats itself.

How Many Stages Should You Describe?

Unlike charts and graphs, process diagrams require you to describe every stage — you cannot select and omit as you would with a map or a bar chart with many data points. However, you can and should group closely related micro-steps into a single sentence where the diagram allows it. For example, if two consecutive stages both involve heating and then cooling, you might describe them in a single complex sentence rather than two short ones.

Aim for approximately 150–190 words for a process diagram response, distributed across:

1. An introductory sentence that paraphrases the diagram title
2. An overview (2 sentences)
3. Body paragraph 1 — first half of the process
4. Body paragraph 2 — second half of the process (or, for a cyclical process, the remaining stages and the return to the start)

Summary and Final Tips

Whether you are writing about a map or a process diagram, the same core principles apply: select carefully, organise logically, vary your vocabulary, and use appropriate grammar consistently.

For map tasks, the key is mastering location language and change vocabulary so that you can describe what happened, where it happened, and how significant the change was — without simply listing every feature. Always lead with an overview that captures the dominant transformation before you move into the detail.

For process diagrams, the key is sequencing connectors and the passive voice. Practise moving through a process using a wide range of connectors — not just “firstly, secondly, finally” — and make sure every stage is covered while still being grouped into coherent paragraphs.

One final tip: before you begin writing any Task 1 response, spend 2 minutes planning your overview. The overview is worth more to your band score than any individual sentence in your body paragraphs, because it demonstrates that you have understood the data or diagram as a whole rather than just cataloguing its parts.

With the right vocabulary and structure, both map tasks and process diagrams become manageable — and even predictable. Practise with real past questions, time yourself strictly, and review your language choices against the phrases in this guide after each attempt.
