Für die Leukämie-Behandlung ist eine Knochenmarkspende oft die letzte Hoffnung.
For leukemia treatment, a bone marrow donation is often the last hope.
The word is a compound of 'der Knochen' (bone) and 'das Mark' (marrow). 'Das Mark' refers to a soft substance inside something, here inside bones.
Das Knochenmark ist für die Bildung von Blutzellen verantwortlich.
Bone marrow is responsible for the formation of blood cells.
You can tell from the context whether the medical or culinary meaning is intended. Verbs like 'spenden' (to donate) or 'transplantieren' (to transplant) point to the medical field, while verbs like 'kochen' (to cook) or 'essen' (to eat) refer to cooking.

'das Mark' and 'das Knochenmark' can mean the same thing when referring to the soft substance inside bones. 'Knochenmark' is more precise and is usually the clearer choice in medicine or biology. 'Mark' is shorter and can also fit in this context, especially when it is already clear that bones are being discussed. Learners may confuse the words because 'Mark' has several meanings: it can also mean parts of plants or a figurative core. When misunderstandings are possible, 'Knochenmark' is safer and more precise.

Der Koch löst das Mark aus den heißen Knochen und streicht es auf Brot.
