FAQs

What's a grammatically correct alternative to "Is duplicate to"?

Instead of "Is duplicate to", use phrases like "is identical to", "is similar to", or "is a copy of" for improved clarity and grammatical correctness.

When is it appropriate to use "duplicate" in a sentence?

Use "duplicate" as a verb (e.g., "Please duplicate this file") or as an adjective (e.g., "This is a duplicate key") but avoid using it as a preposition.

How can I rephrase a sentence using "duplicate" correctly?

Instead of saying "This result is duplicate to that one", say "This result is identical to that one" or "This result "duplicates" that one" depending on the intended meaning.

What's the difference between saying something "is duplicate to" something else versus saying it "duplicates" something else?

The phrase "is duplicate to" is grammatically incorrect. A correct alternative, "duplicates", means it actively makes a copy. For instance, "This machine duplicates the key". To show direct equality, you can use the expression is identical to.
