For the Same vs. Of the Same – Which is Correct?
Both “for the same” and “of the same” are grammatically correct, but they serve different purposes. Use “for the same” when describing an identical purpose, reason, recipient, or replacement. Use “of the same” when showing identity, category, composition, or membership. The surrounding noun and verb determine the natural choice in context.
A related distinction arises when deciding between “one” and “the same,” a topic explored in One vs. The Same.
“For the Same” or “Of the Same” – Which is Correct?
Neither phrase is automatically incorrect. The difference comes from the prepositions for and of. “For the same” usually connects something with an identical purpose, reason, person, recipient, or replacement. “Of the same” usually identifies something as belonging to the same group, type, substance, source, or category.
For example, “She bought a replacement for the same model” refers to a replacement serving the same function or matching the original model. By contrast, “The two samples are of the same material” means that both samples consist of, or belong to, one identical material category.
The Best Trick to Remember the Difference
Use the purpose-versus-identity test. If you can replace the phrase with “intended for the same purpose” or “because of the same reason,” choose for the same. If you can replace it with “belonging to the same type” or “made from the same substance,” choose of the same.
| Word | Part of Speech | Meaning | Example |
|---|---|---|---|
| for the same | Prepositional phrase | For an identical purpose, reason, recipient, or replacement | They returned for the same reason. |
| of the same | Prepositional phrase | Belonging to, consisting of, or matching the same category or identity | The fabrics are of the same quality. |
How to Use “For the Same”
Use “for the same” when for expresses purpose, suitability, exchange, or a reason connected to an earlier statement. The phrase often appears before a noun such as reason, purpose, price, amount, use, or model.
This phrase is neutral and works in casual conversation, academic writing, business communication, and formal prose. However, it is often followed by a noun or a fuller phrase because “the same” alone depends heavily on context.
Example 1: The committee rejected the proposal for the same reason it rejected the previous one.
Example 2: I exchanged the damaged charger for the same model.
Example 3: The storage room can be used for the same purpose as the main archive.
How to Use “Of the Same”
Use “of the same” when of expresses belonging, composition, classification, origin, or association. It commonly appears before nouns such as type, kind, quality, size, color, material, family, or age.
“Of the same” often compares two or more things and emphasizes that they share a defining characteristic. In many sentences, it is followed by a noun: “of the same type” or “of the same material.” The phrase can also appear in expressions such as “two people of the same age.”
Example 1: The laboratory tested two samples of the same substance.
Example 2: Both paintings are of the same period and artistic tradition.
Example 3: The two candidates are of the same age but have very different experience.
Related Concepts
Understanding the roles of the prepositions for and of makes this distinction easier because each preposition contributes a different relationship to the noun that follows.
- Prepositions: Prepositions show relationships between words. For can express purpose, benefit, exchange, or reason, while of can express belonging, composition, origin, or classification.
- Comparison: Both phrases can compare things, but they compare different qualities. “For the same” often compares purpose or reason, whereas “of the same” often compares type, identity, or characteristics.
- Ellipsis: “The same” can replace a noun when the meaning is already understood. For example, “I ordered the same” means “I ordered the same item.”
- Collocation: Certain nouns naturally follow particular prepositions. English speakers commonly say “for the same reason” and “of the same kind,” so learning common word combinations improves fluency.
Examples from Media and Literature
These examples reflect common patterns found in books, films, journalism, and everyday media language. They show how the intended relationship determines the correct phrase.
- News reporting: A report may state that officials met “for the same reason” as they did during an earlier investigation, emphasizing a repeated cause.
- Business writing: A product review may explain that a customer exchanged a device “for the same model,” emphasizing a replacement.
- Historical writing: A biography may describe two leaders as “of the same generation,” emphasizing their shared age group or historical period.
- Science writing: An experiment may compare samples “of the same material,” emphasizing identical composition.
- Fictional dialogue: A character might say, “I came back for the same reason,” referring to a repeated motive or purpose.
