Why this happens to engineers

Translation from another language produces combinations that are logical but not natural in English, for example 'do a mistake' or 'big traffic'. Examiners hear these immediately.

Why this affects engineers: technical reports use numbered points and specifications, which do not translate into discursive paragraphs.

Technical vocabulary is strong, but vocabulary for social and cultural topics in Task 2 is often limited.

A strength to build on: Comfort with reading data makes Task 1 charts and processes easier than for many candidates.

Fix it in four steps

  1. When you meet a new word, note two or three verbs or adjectives that usually go with it.
  2. Use a collocation dictionary for your top ten essay topics.
  3. Replace one weak phrase per paragraph with a stronger natural pair.
  4. Read your essay aloud and mark any combination that sounds odd.

Before and after

Before

People should do more efforts to make a big pollution decrease.

After

People should make more effort to bring about a significant reduction in pollution.

Ten-minute drill: Write five correct collocations for 'decision', 'risk' and 'effect' and use one in a sentence each.

Questions and answers

What is the fastest way for engineers to fix unnatural word combinations?

Learn words in natural pairs such as 'make a decision', 'raise awareness' and 'heavy traffic', not as single words. Collocation errors are among the most noticeable lexical mistakes at Band 6 and below. Technical vocabulary is strong, but vocabulary for social and cultural topics in Task 2 is often limited.

How long does it take engineers to fix unnatural word combinations?

Most learners need two to three weeks. Project deadlines compete with study, so a fixed weekly slot for one timed essay is more reliable than ad hoc practice.

What is a collocation?

A pair or group of words that naturally go together, such as 'strong evidence' or 'pursue a career'. Using them correctly makes writing sound natural.

How do I find collocations quickly?

A learner's collocation dictionary or the example sentences in an online learner's dictionary show the most common combinations.

What does a good practice drill look like for engineers?

How can engineers tell they have fixed unnatural word combinations?

Few phrases in your essay are flagged by a dictionary or a teacher as unnatural.

What should engineers know about their IELTS Writing target?

Engineering registration and skilled migration routes usually set a minimum Writing score. Check the licensing body or visa category for the current number.

Should engineers practise this on Task 1, Task 2 or both?

It shows up in both tasks. Fix it in Task 2 first, because Task 2 carries about twice the weight of Task 1, then check Task 1 with the same checklist. Comfort with reading data makes Task 1 charts and processes easier than for many candidates.
