أو إيهام استلذاذ أي وجدان التلذذ
Or to convey, or suggest, pleasure in uttering the name.
A speaker may repeat a proper name because the act of naming expresses affection, longing, or intimacy. The name then does more than introduce a referent: it also registers the speaker's feeling.
A poet who repeatedly says ‘Laylā’ rather than using a pronoun can make attachment audible in the wording. Nevertheless, emotional delight is not the purpose of every repetition; reference, meter, or another communicative need may also explain a name's use.
