We should avoid the following types of words in summary:
Misused words: The word which conveys something else than what we intended to say should be avoided. For example, “The graph was used to prove the differences.” The correct sentence is “The graph was used to convey the association between the variables.”
Words with unwanted connotations or meanings: Words which convey an unwarranted meaning which the author does not want to say should be avoided. For example: “The questionnaire was administered to participants in their private places.” The right sentence would be “The questionnaire was administered to participants in privacy.”
Pronouns should not be used incorrectly: If the pronoun is not correctly used, the sentence will convey some other meaning. For example: “The scientists collected the information through interview with the priest but he did not like it.” Here, the he in “he did not like it” refers to the priest and not to the researcher. The correct sentence would be “He collected the information through interview with the priest but the latter did not like it.”
Jargon or technical terms: Jargon’s and technical words should not be used in a summary when it is meant for common man. Technical words can be used only when it is essential. For example: “Polygraph helps to identify criminals.” A layman may not understand polygraph. Thus the best way to write it would be “The method used to identify the criminal is known as polygraph.”
Loaded language: Sometimes writing gets confounded and the meaning becomes different from what it is meant to be.
