Which of the following accurately describes the emotional connotation of interjections?

Interjections are linguistic elements that express emotions, feelings, or sudden reactions, often standing alone in a sentence. They can convey a wide range of emotions, from joy and surprise to frustration and anger, allowing speakers to communicate their emotional states directly and effectively. This characteristic makes them unique compared to other parts of speech that might focus more on conveying information or connecting ideas logically.

The other options do not capture the primary purpose of interjections. Logical conclusions are typically drawn from statements that require reasoning rather than emotional expression. Transitioning between ideas involves connecting sentences or statements in a cohesive manner, which interjections do not inherently do. Summarizing spoken language indicates a synthesis of ideas, while interjections are more about immediate and expressive feelings rather than summarizing or providing a conclusion. Therefore, interjections are best understood as expressions of feelings directly, which is why this choice accurately reflects their emotional connotation.
