PTE Describe Image Vocabulary for Maps, Processes, and Photos

Published Updated 10 min read Editorial standards

A learner studies abstract bars, circles, and trend lines and isolates the most important comparison

A map shades three habitats. A process diagram links six stages. A photograph shows people beside laboratory equipment. None of these is a line graph, so a memorized string about “an upward trend” will not help.

For PTE Academic Describe Image, Pearson's current format says an image appears on screen, you have 25 seconds to study it, and you speak for 40 seconds. The task assesses Speaking. Pearson says content is judged through accurate, thorough coverage of the image, including relationships and appropriately grounded conclusions or implications; pronunciation and oral fluency are also scored. The current page also states that an irrelevant or unoriginal response receives no credit and that you must use your own words.

This guide focuses on maps, process diagrams, photographs, and other non-trend visuals. For line and bar charts, use the separate PTE Describe Image trend vocabulary guide. For a wider task map, visit the PTE Academic vocabulary hub and Exam English.

Build from evidence outward

Use three levels:

  1. Visible fact: What is directly shown, labelled, or connected?
  2. Relationship: How do elements compare, occupy space, or form a sequence?
  3. Cautious interpretation: What conclusion is plausible from those details?

Spend most of the response on the first two. An interpretation should remain tied to a visible feature. You do not need to invent a backstory for a photograph or a cause for an unlabelled pattern.

1. Depict: name what the image shows

Depict means show or represent someone or something in a picture, film, or writing. It is transitive: the image depicts a coastal region, not depicts about a coastal region.

Useful patterns:

  • The map depicts + object: The map depicts protected habitats across the island.
  • The diagram depicts + process: The diagram depicts how water moves through the system.
  • X is depicted as Y: The central zone is depicted as densely forested.
  • a photograph depicting + object: a photograph depicting a laboratory team

The object is what is shown. Depict as describes the representation; it does not prove that the real subject has every represented quality.

You can also say shows. Pearson does not require an advanced verb. Use depict only when it helps you form an accurate opening.

2. Salient: select details that matter to the visual's message

Salient describes a feature that stands out as especially relevant or noticeable for the current purpose.

The most salient feature is the concentration of sites along the western coast.

Natural combinations include salient feature, salient contrast, salient difference, and most salient. The word is not a filler for every important point. It performs a selection: among many visible details, which one best organizes the description?

Something can be salient without being visually largest. On a process diagram, a small recycling arrow may be the most salient relationship because it changes a simple line into a cycle.

3. Indicative of: a sign, not proof

Indicative of means serving as a sign or suggestion of something.

The cluster of symbols near the river is indicative of concentrated settlement in that area.

Use be indicative of + noun or gerund. The expression introduces an evidence-based interpretation but does not establish proof or cause. A dark area on a labelled population map may be indicative of high density. The same dark area on an unlabelled photograph is not enough to support that claim.

Do not use indicative for in this frame. Also separate the phrase from indicate, a verb: the legend indicates protected land.

4. Seemingly: mark appearance while withholding certainty

Seemingly means apparently or as it appears, while leaving open the possibility that the full reality differs.

Two seemingly identical containers feed into different stages.

This is useful when a visible resemblance matters but labels reveal a distinction. It can also qualify a photo observation:

A person is seemingly inspecting the equipment.

That sentence is cautious, but it may still be unnecessary if the exact action is not clear. Prefer a visible fact—a person is standing beside the equipment—when the image does not support the stronger verb.

Do not scatter seemingly across every sentence. It is a precision signal, not a fluency ornament.

5. Plausible: a reasonable interpretation, not a fact

Plausible means reasonably possible or apparently valid. It does not mean proved, probable, or certain.

One plausible interpretation is that the shaded corridor links the two habitats.

This frame is helpful when the image supports an implication but does not label it explicitly. State the evidence first. The route connects both reserves; therefore, a plausible interpretation is that it supports movement between them.

Avoid using plausible for a visible fact. If an arrow clearly connects stage three to stage four, the connection is shown; it is not merely plausible.

Understanding is only the first step.

6. Trajectory: reserve it for a path across stages or time

Trajectory describes a path or direction across multiple points. It is not a generic synonym for line or change.

In a process image, it may fit when the diagram genuinely shows movement through a sequence:

The arrows trace the material's trajectory from collection to reuse.

In a map, it may fit a marked route across locations. In a photograph, it rarely helps unless an actual path is represented. One still image of a person holding a box does not establish the object's trajectory.

Use an article or modifier: the trajectory, a circular trajectory, the trajectory from X to Y. Do not say on trajectory with no article.

Maps: location before implication

For a map, prioritize:

  • orientation: north, south-east, inland, along the coast
  • distribution: concentrated, dispersed, clustered, confined to
  • boundaries and connections: borders, links, runs through, surrounds
  • categories in the legend
  • the most salient spatial contrast

Worked map response

Prompt: an imagined map shows two gorilla subspecies across central Africa, with one range west of a river and another range east of it. Several protected areas overlap the eastern range.

The map depicts the distribution of two gorilla subspecies across central Africa. The most salient feature is their separation around the river: one range lies mainly to the west, while the other is concentrated to the east. Several marked protected areas overlap the eastern range, which is indicative of conservation coverage in that region, although the map alone does not show how effective that protection is. Overall, the species occupy distinct but relatively concentrated areas rather than a continuous range.

The answer states locations before interpreting them. It does not invent population totals, causes, or a conservation outcome.

Processes: follow arrows and name the structure

For a process diagram, identify:

  • the starting input
  • the main stages and their order
  • branches, merges, or feedback loops
  • the final output
  • whether the process is linear, cyclical, or partly recycled

Sequence language can be plain: initially, next, after this, before, finally. Add trajectory only if it clarifies movement across several connected stages.

Worked process response

Prompt: an imagined diagram shows used glass collected, sorted, crushed, heated, moulded into new bottles, and returned to retailers; rejected material returns to sorting.

The diagram depicts a largely cyclical glass-recycling process. Initially, used containers are collected and sorted before acceptable glass is crushed and heated. The material's trajectory then continues through moulding, after which new bottles return to retailers. A salient feature is the feedback route: rejected material goes back to the sorting stage instead of leaving the system. This return is indicative of a process designed to recover some material that fails the first inspection.

The response follows the arrows and identifies the loop. Designed to recover is supported by the route; it does not claim a numerical efficiency that the diagram never gives.

Photographs: visible action before inferred purpose

Photographs tempt test takers to invent motives. Separate what you can see from what you infer.

Visible:

Three people are standing around a table containing several electronic components.

Cautious interpretation:

They are seemingly examining the components, although the exact purpose is not labelled.

Unsupported:

The engineers are repairing a failed medical device before an urgent deadline.

The final sentence invents profession, object, failure, and urgency. Fluent fiction is still inaccurate content.

Worked photograph response

Prompt: an imagined photo shows four adults in safety glasses around a workbench. One person points to a small device while another holds a clipboard. Shelves and labelled containers appear behind them.

The photograph depicts four adults gathered around a workbench in what appears to be a technical workspace. The most salient action is one person's gesture toward a small device, while another person holds a clipboard. Their safety glasses and the labelled containers are indicative of a controlled work setting, but the image does not establish the specific industry. The group is seemingly discussing or inspecting the device. Overall, the visible focus is collaborative attention to the object on the bench.

The response uses cautious inference only after concrete details.

A flexible planning frame, not a fixed script

During the 25-second preparation time, write four prompts:

  • type/topic — what kind of image and subject?
  • salient — which detail organizes the response?
  • relations — where, before/after, connected to what?
  • limit — what tempting inference should you avoid?

Then speak in a natural order: overview, main relationship, supporting details, grounded conclusion. This is a planning method, not an official Pearson template, and no wording must be memorized.

Evidence-strength ladder

Compare these claims about a shaded map:

  1. The map depicts three shaded coastal areas. Directly visible.
  2. The shaded areas are concentrated in the north. A spatial relationship.
  3. The distribution is indicative of greater northern coverage. A cautious interpretation, valid if the legend defines the shading as coverage.
  4. It is plausible that access is easier in the north. Possible only if routes or access features provide evidence.
  5. The policy succeeded because northern residents support it. Unsupported cause and attitude.

Move upward only when the visual supplies the evidence.

Common mistakes

  • Using a chart script for every image. Maps need location, processes need sequence, and photos need visible action.
  • Calling every detail salient. Select one organizing feature rather than praising every element as important.
  • Treating indicative of as proof. It signals evidence, not certainty or causation.
  • Using seemingly to disguise invention. A hedge cannot rescue an interpretation with no visual basis.
  • Calling a fact plausible. Clearly shown connections should be stated directly.
  • Using trajectory for one arrow. The word requires a path across multiple points or stages.
  • Inventing a fixed Pearson-approved script. Organize clearly, but answer the actual image in your own words.

Controlled practice

Choose the best completion.

  1. A diagram has seven linked stages. “The arrows trace the material's ______ from extraction to reuse.” trajectory / salience
  2. A map legend explicitly labels dark shading as forest. “The map ______ dense forest in the north.” depicts / corroborates
  3. Two routes visibly meet at one station. “The shared station is the most ______ relationship.” salient / provisional
  4. A photograph shows a person leaning toward and looking closely at a machine's controls, but it does not label the action. “The person is ______ inspecting the controls.” seemingly / conclusively
  5. Several warning symbols surround one stage. “The cluster is ______ additional risk at that stage.” indicative of / proof of
  6. A map shows a broken corridor between habitats. “One ______ interpretation is that connectivity is limited.” plausible / certain

Answers: 1. trajectory, because the diagram shows a path through multiple stages. 2. depicts, because the labelled map shows the forest. 3. salient, because the meeting point is selected as especially relevant. 4. seemingly, because the action is an appearance, not a verified purpose. 5. indicative of, because the symbols are signs rather than proof. 6. plausible, because the conclusion is reasonable but not established as fact.
