The second major pattern is placing an overt expression where a pronoun was expected. After an entity has been mentioned, a pronoun is normally economical; choosing a repeated name, description or demonstrative may nevertheless carry a rhetorical purpose.
Illustration: «جاء خالدٌ، وخالدٌ صادقٌ» could use «هو» in the second clause. Repeating Khalid may place renewed emphasis on the person whose truthfulness is asserted. Without a relevant context, however, repetition is not automatically elegant.
The decisive question is which trait or judgment the renewed explicit wording highlights, not how many times a name appears.
