medulla (plural medullas or medullae or medullæ)
Uncertain. Traditionally compared to Latin medius (“middle”), or Proto-Indo-European *mosgʰos (“brain, marrow”). (Can this etymology be sourced?) De Vaan mentions neither of these theories, and instead prefers a derivation from Proto-Indo-European *smer-u-lo-, from *smérus (“grease, marrow”), with the irregular change from *-r- > -d- resulting from hypercorrection similar to that of *-d- > -r- in merīdiēs (“midday”).
