In wa-dārun lahā bi-l-raqmatayn, dārun introduces another dwelling and lahā connects it with Umm Awfā. Ka-annahā combines the comparative particle ka-anna with the feminine pronoun, and marājīʿu washmin supplies the comparison's predicate.
The tenor is the surviving trace of the residence; the vehicle is a tattoo’s lines on a wrist; the point of likeness is their fineness, diminished visibility, and scattered appearance. The comparison is about memory and traces, not a direct compliment about adornment.
