The close of the chapter points to constructions of address and specification (الاختصاص). An expression resembling a vocative may instead emphasize the speaker's membership in a class or a selected personal quality. Specification is thus not always a call to a separate person.
«أَنَا أَفْعَلُ كَذَا أَيُّهَا الرَّجُلُ»
I perform this, being the man that I am.
Here “ayyuhā al-rajul” need not summon another individual; it can highlight the speaker's own characterization. By contrast, urging (الإغراء) directs attention toward an act the addressee is encouraged to undertake. The distinction depends on the phrase's place in the full utterance.
