IELTS Line Graph Vocabulary

To describe an IELTS writing task 1 line graph well and earn a high band score, you’ll need the following IELTS Line Graph Vocabulary, to show the examiner a variety of words to demonstrate upward and downward trends, as well as significant elements.

IELTS line graphs depict change through time, and when writing your report, you must use a variety of language and words.

Let’s build some vocabulary. Here is a list of verbs, adverbs, adjectives and nouns that you need to use to describe the IELTS Line Graph.

Verbs & Nouns

The verbs and nouns that can be used to describe a line graph in IELTS writing task 1 are listed below.

IELTS Line Graph Vocabulary verbs

Upward trend

  • rise / a rise
  • increase / an increase
  • climb / a climb
  • grow / a growth
  • go up
  • Jump
  • Rocket

Downward trend

  • decrease / a decrease
  • drop / a drop
  • fall / a fall
  • decline / a decline
  • Go down
  • Plummet
  • Plunge.

Note that “plunge” and “plummet” do not take adverbs because what they
mean is a big decrease.
We can say “decreased considerably/sharply/dramatically/significantly/substantially” or “plunged”,
or “plummeted”.
But, we must not say,
“plummeted considerably/sharply/dramatically/significantly/substantially
or
“plunged considerably/sharply/dramatically/significantly/substantially

No need to use those two verbs “plunge” and “plummet” with an adverb. Decreased sharply equals plummeted. They mean the same thing.

Likewise, “rocket” does not take adverbs. So to as y increased significantly, rose sharply, they mean the same thing as rocket. A big/sharp increase, so no adverbs for rocket.

 

Other vocabulary

  • fluctuate / a fluctuation
  • dip / a dip
  • remain steady
  • remain stable
  • remain unchanged
  • level off
  • peak at
  • reach a peak of
  • hit a high of
  • hit a low of
  • bottom out
  • plateau

Mistakes when using words will affect your band score. This includes spelling.

  • Band 6 = some vocabulary errors.
  • Band 7 = few vocabulary errors.
