نضخ

Core meaning

To gush forth with force and abundance, like a spring under pressure.

Uses

1. نَضَّاخَتَانِ → "gushing" : intensive form in the dual: the two springs never cease gushing.

   • «فِيهِمَا عَيْنَانِ نَضَّاخَتَانِ» — "In them both, two gushing springs" (55:66)

Evidence from the text

Sole occurrence (55:66). The second pair of gardens receives two springs that gush, where the first had two springs that flow (55:50): the intensive form says the force and abundance of the flow, not a mere trickle.
