What term refers to the recognized methods of expressing a meaning indirectly?

The term that refers to the recognized methods of expressing a meaning indirectly is linguistic conventions. These conventions encompass the ways in which language can be used to convey ideas, emotions, and messages without stating them explicitly. Linguistic conventions include idioms, metaphors, and other forms of figurative language that imply meaning beyond their literal interpretation. They are essential in communication as they add depth and nuance, helping speakers and writers convey complex ideas and emotions in a more relatable or impactful way.

In contrast, the other choices do not pertain to the concept of indirect expression. A selection fallacy relates to a logical error in reasoning or argumentation. An appeal to authority involves using the opinion of an expert to validate an argument but does not focus on the indirect expression of meaning. Civil disobedience is a method of protest that involves violating laws or regulations deemed unjust, which also does not relate to linguistic expression.
