A precise summary is a compressed model of the source. It keeps the central propositions and relationships while removing repetition, illustration and lower-priority detail. Good summary writing therefore depends first on deciding what the text is doing, not on shortening sentences one by one.
Find the argument skeleton
Before writing, identify the central claim, major reasons, necessary qualifications and conclusion. Examples and anecdotes may help the original text persuade or explain, but they often disappear in a summary once their underlying point has been captured.
Compression is not deletion at random
Removing every second sentence can destroy logic. Instead, combine details that perform the same function. Three examples of transport delays may compress into “repeated service disruptions”.
Preserve scope and qualification
If the writer says a policy “can help under certain conditions”, summarising it as “the policy works” changes the claim. Small qualifiers may be essential even when word limits are tight.
Use category words
Specific items can often be compressed under a meaningful category. “Buses, trains and shared bicycles” may become “transport options” if the individual differences are not important to the argument. Good abstraction saves words without losing structure.
Worked example
Source idea: A passage gives three examples of employees losing time to unnecessary meetings, then argues that meetings are useful only when a clear purpose requires real-time discussion.
Summary: “Unnecessary meetings can consume substantial working time; they are most useful when a defined task genuinely requires synchronous discussion.” The examples disappear, but the problem, qualification and conclusion remain.
Avoid commentary
A summary reports the source’s ideas. “The writer correctly argues…” adds your evaluation. Unless the task asks for response or critique, keep your judgment separate.
Avoid source-language dependence
After identifying the meaning, look away from the original and reconstruct the point. This reduces copying and encourages compression at the idea level rather than word substitution.
The summary pipeline
- Identify the central question or topic.
- Mark each paragraph’s function.
- Extract only major propositions and necessary qualifications.
- Group repeated or parallel details.
- Rewrite from the meaning map.
- Check that no claim has become broader or more certain.
- Remove remaining redundancy.
Precision audit
- Could a reader reconstruct the source’s main position?
- Did I preserve important causes, contrasts and conditions?
- Did examples disappear only after their function was captured?
- Did I add any personal judgment?
- Can another phrase be compressed without losing meaning?
