Rainer
Meaning
counsel army (regin 'counsel' + heri 'army'); famously borne by Rainer Maria Rilke, Austrian-Bohemian poet
The story
Rainer is an old Germanic name built from regin, counsel, and heri, army: the counselor of the army, a stern meaning for a name now attached to one of poetry's most delicate voices. Rainer Maria Rilke was actually born René, in Prague in 1875, and adopted the more Germanic Rainer in his twenties, encouraged, the story goes, by his companion Lou Andreas-Salomé, who thought it the stronger name. Under it he wrote the Duino Elegies, the Sonnets to Orpheus, and Letters to a Young Poet, the slim book of advice that has been pressed into the hands of young writers for a century. In the United States the name barely exists: it first registered in the 2020s and remains genuinely rare, a soft-spoken European classic that poetry lovers will place immediately.
