Something I’ve noticed that I’ve never seen remarked on: English has weird pairs of opposite where only one is Germanic/Nordic and the other one is “made up” or otherwise unclear. Examples: German: man Unclear: woman (not frau or kvinna) German: white (weiss/vit/etc) Unclear: black (bläck means ink in Swedish but?) Swedish: up Unclear: down (not undan or ner) German: full (voll) Unclear: empty (not leer or tom)
