For instance, if you are writing a report about climate change, information about weather patterns would be considered relevant. Unsuitable - This means something that is not appropriate or fitting for a specific purpose. In our example, any information that does not relate to climate change, such as a discussion about sports, would be unsuitable and thus the opposite of relevant. In the multiple-choice options provided: A) pertinent - This means relevant or applicable, so it is not the opposite. B) courteous - This refers to being polite, which is unrelated to relevance. C) obstinate - This means stubborn, which does not pertain to the idea of relevance. D) unsuitable - This is the correct answer, as it signifies something that does not fit or is not relevant to a given context and is indeed the opposite of relevant. ; Examples & Evidence: For example, when discussing suitable clothing for a formal event, wearing shorts would be considered unsuitable because it does not fit the context.
