In a manner that is concurrent or simultaneous; in agreement or with concurrence.
From concurring + -ly (English adverb-forming suffix). This adverb formation allows description of actions or events that happen in a manner characterized by concurrence or simultaneity.
Concurringly is so rare that finding it in actual use is like finding a linguistic treasure—it appears almost exclusively in very formal legal or philosophical writing where scholars need to describe something happening 'in a concurrent manner' rather than just 'at the same time.'
