make an exact copy
To make something that is exactly the same as another thing.

to duplicate [something]
자주 하는 실수：
Learners sometimes use "double" instead of "duplicate" (e.g., *double a file*). Use "duplicate a file" or simply "copy a file" when you mean to make an exact copy, especially in technical or office contexts.

an exact copy of something
Something that is exactly the same as another thing; a copy.
사용 패턴：
a duplicate of [something]
자주 하는 실수：
Learners may say "make a duplicate of copy" or "duplicate copy" when only one word is needed. Say "make a copy" or "make a duplicate of the contract," not *"duplicate of copy".* Note that native speakers do sometimes say "duplicate copy" in speech, but it is considered redundant in careful writing.
유의어

3
repeat work or process needlessly
To do the same work or process again when it is not needed.
사용 패턴：
to duplicate [work/process/effort]
자주 하는 실수：
Learners sometimes use only "repeat" where "duplicate" is better in business or technical contexts, especially with "work," "efforts," or "data." "Repeat" can be neutral or positive, but "duplicate" here often suggests waste or error.
유의어
repeat (General word; does not always suggest that the extra action is unnecessary.)
|
overlap (Suggests two people or processes are doing the same thing at the same time.)
반의어
streamline (Opposite because it removes extra or repeated work instead of creating it.)

To reach the same result or success again as before, or as another person or group.
사용 패턴：
to duplicate [someone's/its] success/results

Learners may think this verb always means making a physical copy. In sports, business, and science, "duplicate" often means to reach the same result again, not to copy an object.
유의어
match (Emphasizes being equal in level or quality, not necessarily literally copying.)
|
recreate (Focuses on producing the same effect or experience again.)
