Which term refers to a statement that is well-chosen or suited to the circumstances?

The term "felicitous" refers to a statement that is particularly appropriate or well-suited to the context in which it is made. It carries a connotation of being not only suitable but also pleasing and well-expressed. When something is described as felicitous, it signifies that it effectively captures the intended meaning and resonates well with the audience or situation.

In this context, the other terms do not convey the same meaning. For example, "accidental" suggests something that happens by chance and lacks intentionality or suitability. "Unfortunate" implies that a statement is regrettable or unlucky, and thus does not align with the idea of being well-chosen. Lastly, "irrelevant" denotes a lack of connection or relevance to the subject matter at hand, clearly contrasting with the idea of an appropriate and well-suited statement.
