Different words are not automatically different modes of bayān. Two expressions may communicate the same meaning with essentially equal explicitness; in that case the variation is mainly lexical rather than a difference in clarity of indication.
“Zayd is generous” and “Zayd is openhanded” may function as similarly direct descriptions. Merely swapping them does not necessarily illustrate the distinctive question studied in bayān. “Zayd's table is always open,” however, requires an association with hospitality to convey generosity.
When comparing expressions, ask three separate questions: Is the main intended meaning the same? Is the expression different? Does the route and degree of clarity genuinely change?
