The antonyms for the word "ex tractions" would be "insertions" or "additions." An extraction means to remove or take something out, so an insertion or addition would be the opposite of that action. For example, in dentistry, an extraction is when a tooth is removed from the mouth. The opposite of this would be an insertion, which is when a prosthetic tooth is added to the mouth. In the context of computer programming, extraction refers to the process of extracting data from a source, while insertion refers to the process of adding data into a database or file.
