Finally a long lost vocab! :D
Is not "abnehmen" acceptable here
Nein. No, it does not fit. It either means to take something off someone /somewhere like "Ich nehme das Bild ab" - I take the picture down or it means to lose weight "Ich will abnehmen" - I want to lose weight.
Apparently a different root, but Fleck and freckle are not so far away in my head, so the mnemonic might serve you too!
