This is one of the site’s deepest example collections: 300 original examples organized across 6 practical categories. Search, filter, and compare patterns without reading the list in order.
A strong use of an infinitive phrase makes its grammatical job clear—noun, adjective, or adverb—keeps attached modifiers close to what they describe, and avoids dangling or overloaded constructions that make the sentence harder to parse.
Use these fuller examples to see what changes between a recognizable pattern and a finished piece of writing. The examples are original or explicitly illustrative, so they demonstrate structure without inventing real-world evidence.
Draft
Purpose is an adverbial function, not a direct object of “opened.”
Why it works: Infinitive phrase: “to verify the original wording.” It modifies “opened” by explaining purpose.
Compare
Surface “to + verb-related form” patterns need grammatical analysis rather than a visual shortcut.
Why it works: In the first sentence, “to” is a preposition followed by a gerund phrase. In the second, “to review the file” is an infinitive phrase.
These transformations make the hidden planning step visible so the template does not become a fill-in-the-blanks substitute for judgment.
Starting material: She opened the file to check.
Result: She opened the file to check the date on the signed version.
Starting material: He looks forward to review the report.
Result: He looks forward to reviewing the report.

| Recognition | Identify the infinitive marker plus verb and any objects, complements, or modifiers that belong to the phrase. | The phrase boundary is clear before its sentence function is labeled. |
| Sentence roles | Distinguish purpose/adverbial infinitives from noun-like complements, subjects, and adjective-modifying infinitives. | The label explains what the infinitive phrase does in the sentence. |
