1. IELTS Line Graph Verbs & Nouns
Below are lists of verbs and nouns that can be used to describe a line graph in IELTS writing task 1. You should alter your sentences to use the noun form of the word and the verb form of the word.
Upward Trend Words
- to rise / a rise
- to increase / an increase
- to climb / a climb
- to grow / a growth
- to go up
Past Tense Verbs:
- to rise / rose
- to increase / increased
- to climb / climbed
- to grow / grew
- to go up / went up
Downward Trend Words
- to decrease / a decrease
- to drop / a drop
- to fall / a fall
- to decline / a decline
- to go down
Past Tense Verbs:
- to decrease / decreased
- to drop / dropped
- to fall / fell
- to decline / declined
- to go down / went down
- Question: Can you use the verb “increase” and the noun “an increase” in the same writing or is it considered repetition of words?
- Answer: You can definitely use the verb and noun form of the same word. This shows great flexibility that you can change word form. Your task is to show the examiner this flexibility. You will use these verbs and nouns in all line graphs because all line graphs show upward and downward trends.
Other Vocabulary
- to fluctuate / a fluctuation
- to dip / a dip
- to remain steady
- to remain stable
- to remain unchanged
- to level off
- to rocket / to soar
Peaks & Lows
- to peak at
- (reach) a peak of
- hit a high of
- hit a low of
- bottom out
- plateau
Tips: You will use the above words according to what is shown in the line graph you are given. Fluctuations are when a line goes up and down repeatedly. A dip is when the line goes down but then returns to its previous point. Nearly all line graphs will have a peak, which means the highest point. Each line only has one peak, which is good to highlight in your report. To rocket and soar are both verbs that describe extremely dramatic increases. Never use these two verbs unless the increase truly is dramatic.
Mistakes when using words will affect your band score. This includes spelling.
- Band 6 = some vocabulary errors.
- Band 7 = few vocabulary errors.
