Etymology

Origin of sonder

Coined in 2012 by U.S. writer John Koenig in his blog The Dictionary of Obscure Sorrows; perhaps partly based on French sonder “to probe, plumb,” of unclear origin, apparently either akin to sound ³ ( def. ), sound ⁴ ( def. ) or from Vulgar Latin subundāre (unrecorded) “to dive, plunge” (ultimately from sub sub- ( def. ) + unda “wave”); perhaps partly based on German sonder- “separate, special” ( see also sundry ( def. ))
