أَيُّهَا الرَّجُلُ
“O man!”—in specification, “I, as a man …”
The sequence contains ayy(u), a vocative-looking head; hā, a particle of attention; and al-rajulu, a nominative follower. In this setting the rhetorical function is identification of a characteristic relevant to the speaker.
A semantic or analytic paraphrase such as akhuṣṣu (“I single out”) helps explain specification, but it must not lead to treating the actually expressed phrase as though the words “akhuṣṣu al-rajula” were literally spoken.
