«فَاسْتَطْلَعْتُهَا طَلْعَ الشَّيْخِ وَبَلْدَتَهُ»
I asked her about the elder’s identity and his home town.
Istaṭlaʿa is a form X verb meaning to seek information or discover what is hidden. The narrator asks who the elder is and where he comes from. Personal details and place of origin together give a stronger clue than a name alone.
