An overt expression can retain lexical information that disappears in a bare pronoun. Repeating a title such as «العالم», «الكريم» or «الظالم» recalls a trait and makes it part of how the following assertion is heard.
For illustration, in «جاء القاضي، والقاضي عادلٌ», repeating “the judge” can focus attention on the relation between judicial office and justice. If only reference tracking matters and no such focus is intended, the pronoun is more economical.
Praise and blame require contextual grounding. The same title can convey honor in one setting and irony in another.
