Etymology

The word "concerning" originates from the verb "concern," which derives from Middle French concerner (to relate to) and Latin concernere (to sift, mix, or perceive). The Latin roots are con- (together) + cernere (to sift or decide). Over time, "concern" evolved to mean "to be relevant to" or "to cause worry," and the present participle form "concerning" adopted dual roles: as a preposition ("regarding") and an adjective ("worrying"). The suffix -ing marks its participial function, linking it grammatically to both verbal and adjectival uses.
