Which functional category of discourse is focused on expressing one's own thoughts or feelings?

The choice of 'Personal' as the correct answer is appropriate because this category of discourse is specifically designed for the expression of an individual's own thoughts, feelings, and experiences. Personal discourse allows speakers or writers to communicate their inner emotions, opinions, and reflections, enabling a deeper connection to their unique experiences.

This type of discourse is foundational in settings where individuals share personal narratives or engage in self-expression, such as in journals, personal letters, or reflective essays. In these contexts, the emphasis is on the subjective perspective of the individual, which aligns perfectly with the goal of conveying their personal insights or sentiments.

In contrast, other categories such as 'Directive' focus on influencing or guiding others' actions, and 'Interpersonal' involves interactions that foster social relationships but may not center on individual emotions. 'Imaginative' discourse relates to creativity and storytelling rather than personal expression, thereby distinguishing it from the focus of personal discourse.
