Clear English does not begin with complicated vocabulary. It begins with a dependable sentence spine: who or what + what happens. Once that spine is in place, you can add time, place, reasons, and opinions without losing your reader.

Start with the sentence spine

The subject tells us who or what we are talking about. The verb tells us what happens. Everything else adds useful detail around that core. Finding this spine first makes longer sentences easier to understand and edit.

Part	Job	Example
Subject	Who or what the sentence is about	The students
Verb	The action or state	completed
Extra detail	When, where, how, or why	the project on Friday

Build common sentence patterns

Pattern	Use	Example
Subject + verb	A complete action or event	The train arrived.
Subject + verb + object	An action that affects something	The students completed the project.
Subject + be + complement	A description or identity	The instructions are clear.
Subject + verb + detail	An action with time, place, or manner	The train arrived at the station early.

Add detail in a useful order

Start with the core meaning, then add the detail your reader needs. Time and place often come near the end, while a reason can follow the main idea. Keep a modifier close to the word it describes so the reader does not have to guess.

Unclear: The students discussed in the library the difficult project. Clearer: The students discussed the difficult project in the library.

A simple editing routine

Circle the main verb. If you cannot find one, the sentence may be incomplete.
Ask “Who or what?” to find the subject.
Move extra details next to the word they describe.
Read the sentence aloud once. If you run out of breath, look for a shorter version.

Avoid fragments and run-ons

Problem	What is missing or wrong	Better version
Fragment: Because the train was late.	It has a reason but no main clause.	Because the train was late, we missed the meeting.
Run-on: The train was late, we missed the meeting.	Two complete ideas are joined incorrectly.	The train was late, so we missed the meeting.
Unclear reference: It was difficult.	The reader may not know what it means.	The final exercise was difficult.
