Where it comes from
From albedo, a physics term that describes the proportion of light reflected by a substance (from the Latin term for whiteness). Ambedo refers to the tendency both to reflect and to absorb. Coined by American author and neologist John Koenig in 2011, whose project, The Dictionary of Obscure Sorrows, aims to come up with new words for emotions that currently lack words.
