Rhetorical analysis separates three questions: What is the context?, What form does it require?, and Has the speaker actually used that form?
TermRole in an example
ḤālThe listener already knows the topic
Muqtaḍā al-ḥālA brief statement without needless detail
MuṭābaqahThe speaker actually supplies a clear concise answer
If the listener is unfamiliar with the subject, explanation may be required instead. Brevity and expansion do not have fixed rhetorical value independently of context.
