act of putting something in
The act of putting one thing inside or into another thing or place.
用法模式：
the insertion of [something] into [something]
常见错误：
Learners sometimes confuse "insertion" (a noun) with the verb "insert" and say *"I insertion the card"* instead of "I insert the card" or "the insertion of the card." Some also incorrectly use "insertion" when they mean "entrance" (the way into a building), which is a different noun.
近义词
entry (More general and less technical; often used for going into a place, while "insertion" focuses on the physical act of putting one thing into another.)
|
placement (Emphasizes the final position rather than the act itself.)
反义词
removal (Describes taking something out, which is the opposite of putting it in.)
|
extraction (Focuses on pulling something out, often with effort, opposite to inserting it.)

added text or material
New words or material that someone adds to writing, speech, or another piece of content.
用法模式：
an insertion in [a text / a document / a script]
常见错误：
Learners sometimes use "insertion" when they simply mean "sentence" or "word," without the idea of it being added later. "Insertion" should only be used when something is added into existing content.
近义词
addition (Very general; does not always suggest that something is placed inside existing text, which "insertion" does.)
|
interpolation (More formal and technical; often suggests inserting material that may not be original.)
反义词
omission (Refers to leaving something out or removing it, opposite to adding it in.)
|
deletion (Specifically means removing text or material that was there before.)

single advertisement placement
One time that an advertisement appears in a newspaper, on TV, online, or in another medium.
用法模式：
[number] insertions in [a newspaper / a magazine / a campaign]
常见错误：
Learners may misunderstand "insertion" here as a physical flyer or paper instead of the single event of showing the ad. In advertising, an "insertion" usually means one appearance of an ad, not a piece of paper you can hold.
近义词
placement (Common in advertising; slightly broader, can include where and how the ad appears, not just the count of times.)
|
spot (Often used for TV or radio; emphasizes the specific time slot rather than the abstract event of insertion.)
反义词
cancellation (Refers to stopping a booked insertion so the ad no longer appears.)

added genetic segment
Extra DNA or RNA that is added into a normal genetic chain.
用法模式：
an insertion in [a gene / the genome / the sequence]
常见错误：
Learners may confuse "insertion" with the general idea of "mutation" and not realize it specifically means that extra genetic material has been added, not just changed or removed.
近义词
insertion mutation (More specific term highlighting that the insertion changes the genetic code.)
反义词
deletion (A change where genetic material is removed, the opposite of an insertion adding material.)
|
loss-of-function mutation (Often results from deletions or other changes that remove function, contrasting with insertions that add bases.)
