8 Preposition Examples
Use these examples to study structure, specificity, tone, and variation. They are demonstrations—not claims about a real person or organization unless the example itself makes that explicit.
What to notice in the examples
Clear preposition choice matches ordinary English usage and the exact relationship intended, especially in fixed combinations where near-synonyms such as in, on, at, to, and for are not interchangeable.
- Identify the relationship being expressed.
- Choose the conventional preposition for that meaning.
- Keep the prepositional phrase close to the word it modifies when ambiguity is possible.

The article focuses on urban heat.

Keep the underlying decision or pattern, then replace the subject, evidence, relationship, constraints, and tone with details that belong to your situation. If your final line still works after swapping only one noun, it may be too close to the example.
