Build Task 1 vocabulary by function, not by chart

Academic Task 1 repeats the same jobs across line graphs, bar charts, tables and pie charts: describe change, compare size, highlight extremes and write an overview. Learning vocabulary by those functions is more efficient than separate lists for every visual type.

Map and process tasks need extra location and sequence language, but your core trend and comparison bank still does most of the work for data tasks.

Trend verbs: what happened over time
Degree adverbs: how fast or how much
Comparison phrases: which was larger, closer or highest
Overview frames: main features without listing every number

Trend verbs you can trust

Vary verbs, but keep tense consistent with the time period on the chart. Past dates usually need past simple. Forecasts may need will or is expected to.

Direction	Neutral	Strong / fast	Slow / small
Up	increase, rise, grow, climb	surge, soar, leap	edge up, inch up, rise slightly
Down	decrease, fall, decline, drop	plunge, plummet, sink	dip, ease, fall slightly
No change	remain stable, stay constant, level off	stabilise after a rise/fall	fluctuate around a level
Up then down	peak at, reach a high of	hit a peak before falling	rise to a high and then decline
Down then up	bottom out at, reach a low of	recover from a low	fall to a low and then rebound

Useful sentence frames	Example
X rose from A to B between ...	Car ownership rose from 35% to 48% between 2005 and 2015.
X peaked at ... in ...	Tourist arrivals peaked at 2.1 million in July.
After peaking, X fell to ...	After peaking in 2018, sales fell to just under 900 units.
X remained relatively stable at around ...	Unemployment remained relatively stable at around 5%.
X fluctuated between A and B	Weekly prices fluctuated between $12 and $18.

Degree, comparison and proportion language

Degree adverbs stop every sentence sounding identical. Comparison language is essential for bar charts and tables with categories. Proportion phrases matter for pie charts and share data.

Type	Bank	Example
Degree	slightly, gradually, steadily, sharply, dramatically, significantly	Exports rose sharply in the final quarter.
Comparison	higher than, lower than, twice as high as, almost equal to, the highest / lowest	Country A was almost twice as high as Country B.
Ranking	ranked first, came second, was the least popular	Walking ranked first among daily commute modes.
Proportion	accounted for, made up, represented, constituted	Renewables accounted for just over a third of supply.
Approximation	about, around, roughly, just under, just over, approximately	Just under 40% of respondents preferred online learning.

Repetitive

Weak report language

Same verb and vague comparison.

•The number increased. Then it increased again.
•A was big. B was small.
•Many people liked cars.

Precise

Stronger report language

Varied verbs and measurable contrast.

•The figure rose steadily, then levelled off.
•A was significantly higher than B.
•Cars accounted for the largest share.

Numbers, time phrases and safe quantifiers

Task 1 also needs clean ways to place figures in time and to talk about amount without inventing false precision. These frames transfer across almost every data chart.

Need	Useful frames	Example
Exact figure	stood at, was, reached	In 2012, the figure stood at 18%.
Range over time	from ... to ..., between ... and ...	Output rose from 2.1 to 3.4 million tonnes.
Time anchor	over the period, during the final year, by 2020	By 2020, renewables had become the second-largest source.
Large share	the majority of, a substantial proportion of	The majority of trips were made by public transport.
Small share	a minority of, a small fraction of, only a tiny share	Only a tiny share of households used solar power.
Difference size	a gap of, a difference of, narrowly higher than	There was a gap of nearly 15 percentage points.
No data drama	relatively, comparatively, broadly similar	The two regions remained broadly similar after 2015.

Overview, process and map essentials

An overview needs big-picture language, not a second data dump. Process and map tasks recycle a smaller set of verbs and prepositions that you can prepare in advance.

Task need	Useful language	Example
Overview opener	Overall, In general, It is clear that	Overall, both cities grew, but City X rose more sharply.
Main feature	the most striking feature, the largest change, a clear difference	The most striking feature is the decline in coal use.
Process sequence	first, next, then, after that, finally, subsequently	The mixture is heated and then cooled before packaging.
Process verbs	is collected, is filtered, is transported, is converted into	Waste water is filtered before it is released.
Map location	to the north of, adjacent to, opposite, replaced, expanded	A car park was added to the north of the station.
Map change	was converted into, was demolished, was extended, was constructed	The library was converted into a community centre.

1Collect 8 trend verbsFour up, two down, one stable, one peak/bottom. Practise them on any line graph.
2Add 6 comparison frameshigher than, the highest, twice as, almost equal, ranked first, accounted for.
3Write one overview onlyForce yourself to name two main features without copying numbers into the overview.
4Specialise lastAdd process verbs or map prepositions only after the core bank is automatic.

How many Task 1 words do I need?+

A controlled bank of roughly 80-100 functional phrases covers most data tasks. Depth of accurate use matters more than memorising 300 near-synonyms.

Can I use the same verbs in every report?+

Some repetition is normal, but vary at least the main trend verbs and comparison structures so Lexical Resource does not look limited.

Should I learn different lists for bar charts and line graphs?+

Learn by function first. Add only small extensions for maps and processes.

Is soared always better than increased?+

No. Choose the verb that matches the size and speed of change on the chart.

What should I practise next?+

Write one timed Task 1 using only this bank, then check overview quality and verb accuracy in Writing Checker.
