How to Understand Long Sentences in English
· Updated
To understand long sentences in English, find the main subject and its complete verb phrase, then connect the surrounding clauses to that core. Keep the words that complete the message, and restore details that identify people, give reasons, or set conditions. A shorter version is a temporary reading aid, not permission to discard half the sentence.
Why can familiar words form a difficult sentence?
A sentence can contain several clauses, each with its own grammatical job. A main clause can stand as a sentence. A subordinate clause depends on a larger construction, perhaps describing a noun or supplying a reason. Several familiar actions can therefore appear inside one sentence without being equally central to its structure.
Consider this constructed example. All examples and the practice passage below are written for this guide:
The report that the research team published after the trial ended raised several questions about the new treatment.
The verbs published and ended arrive before raised. But the report didn't publish anything, and the report didn't end. The core statement is The report raised several questions about the new treatment. The team published the report, and the trial ended before that publication.
Breaking the sentence into those relationships reveals more than translating its words one at a time. The problem to solve is which subject belongs with which verb.
How do you understand long sentences in English step by step?
Use the following sequence on one sentence that blocks the paragraph. It is a practical reading procedure based on English clause structure, not a tested formula for learning speed.
- Read through to the period. Form a provisional idea of what the sentence says before marking it.
- Locate the verb phrases and their subjects. Keep combinations such as has been delayed or did not approve together. Decide which clause supplies the main statement.
- Write a short core. Retain an object or other completion if the verb needs it. The report raised leaves the message unfinished; The report raised several questions gives you something to work with.
- Attach the other parts. Ask what each one describes or contributes: which report, when it appeared, why something happened, or under what condition.
- Check the complete meaning. Restore the details and paraphrase the whole sentence. Preserve negatives, contrasts, and conditions.
Here's a second example:
Although the tickets that Elena booked last month were expensive, she decided to keep them because the trip mattered to her father.
Begin with she decided to keep them. Resolve the references: she is Elena, and them refers to the tickets. Then restore the relationships:
- That Elena booked last month identifies the tickets.
- Although ... were expensive sets up a contrast with her decision to keep them.
- Because the trip mattered to her father gives her reason.
A full paraphrase could be: “Elena decided to keep the expensive tickets she had booked the previous month because the trip was important to her father.” A version saying that she kept them because they were expensive would connect the wrong reason to the decision.
If most sentences in an article require this much unpacking, use an easier version to establish the subject before studying one original sentence. Comprehensy can adapt an article to your selected level. Return to the original to inspect how its parts connect, and compare the two meanings rather than assuming that every detail survived the adaptation.
How do you find the main subject and verb?
Look for a subject and verb phrase that form a complete statement, allowing for material inserted between them. The subject may be a long noun phrase rather than a single name. A nearby noun doesn't automatically belong with the next verb.
The photographs that my cousins found in the attic have been donated to the museum.
The full subject is The photographs that my cousins found in the attic. For your first reading, its central noun is photographs, and its main verb phrase is have been donated. My cousins found belongs to the clause describing the photographs.
The passive construction also matters. The photographs received the action; they didn't donate anything. The sentence doesn't name the donor. Avoid turning a grammatical subject into the person performing an action when the verb says otherwise.
Not every sentence has just one main clause:
The train was late, but the passengers who had reserved seats stayed on the platform.
Here, The train was late and the passengers ... stayed on the platform are main clauses joined by but. Keep both statements and their contrast. Searching for one “real” verb would throw away part of the sentence.
Which details can you temporarily set aside?
Set a detail aside only long enough to see where it attaches. Its grammatical dependence doesn't tell you whether its information matters.
Relative clauses describe a person or thing. Compare:
The employees who work nights will receive an extra payment.
The employees, who work nights, will receive an extra payment.
In the first sentence, who work nights identifies the employees receiving the payment. You can't conclude that every employee qualifies. In the second, the commas present night work as additional information about the employees already being discussed. The payment applies to that group.
The difference is small on the page and substantial for a payroll department. When reconstructing the message, preserve which group the sentence identifies.
Some clauses complete a verb rather than describe a noun:
The manager said that the delivery would arrive after lunch.
That the delivery would arrive after lunch supplies what the manager said. A note containing only The manager said hasn't recovered the message. Also preserve the reporting relationship: this is the manager's statement about the delivery.
What if there is no obvious connecting word?
English sometimes leaves out a relative pronoun when it is the object of the relative clause:
The article Maya recommended explains the changes clearly.
Read this as The article that Maya recommended explains the changes clearly. Maya recommended the article; the article explains the changes. Maya recommended sits inside the description of the subject, even without that marking its beginning.
You may also encounter a shorter clause with an -ing form or a past participle:
The passengers waiting near the entrance were asked to move.
The documents attached to the email contain the instructions.
For these examples, expand waiting near the entrance to who were waiting near the entrance, and attached to the email to that are attached to the email. The main verb phrases are were asked and contain.
This expansion is a check on these particular structures, not a rule that every -ing word describes the nearest noun. If your expansion produces a different actor or an implausible message, check the construction in a grammar reference. The method for investigating grammar through reading explains how to verify a recurring pattern.
Explain why the library's reopening was postponed
Read the whole passage before analyzing the second sentence:
A neighborhood library is preparing to reopen. Although the rooms that volunteers painted last week are ready, the opening has been postponed because the new shelves have not arrived. The librarian said the books donated by local residents would remain in storage until the shelves were installed.
Try these tasks before checking the answers:
- Write the main statement of the second sentence, keeping its complete verb phrase.
- Identify who painted the rooms and when.
- Explain the reason for the postponement. Were the rooms unfinished?
- In the final sentence, identify what donated by local residents describes.
- Explain what the librarian said would happen to the books.
Check your reading. The second sentence's main statement is the opening has been postponed. Volunteers painted the rooms last week. Those rooms are ready, but the shelves haven't arrived, which is the reason for the delay. A summary blaming unfinished painting reverses the contrast.
In the final sentence, local residents donated the books. The main reporting structure is The librarian said ..., with that omitted. The reported message is that the donated books would stay in storage until the shelves were installed. It doesn't say that the books had already been placed on shelves.
Now close the passage and explain the reopening problem in two sentences. Check your explanation against the original. Naming the clauses is useful only if you can recover the situation they describe.
