der Kern

'Der Kern' can translate to both 'pit' (for stone fruits) and 'core' (for apples/pears). The specific meaning depends on the fruit.

'Der Kern' also means 'core' in a more abstract sense (e.g., 'der Kern eines Problems' - the core of a problem, or 'der Erdkern' - the Earth's core).

For nuts, 'der Kern' refers to the edible part inside the shell, like 'ein Walnusskern' (a walnut kernel).

Often confused with 'der Kern' because both relate to parts of a fruit.

'die Schale' refers to the peel or skin of a fruit, the outer layer. 'der Kern' is the inner, central part.

Der Apfel hat eine rote Schale und einen kleinen Kern. (The apple has a red peel and a small core.)

Related to fruits, leading to potential mix-ups.

'das Fruchtfleisch' is the pulp or flesh of a fruit, the edible part surrounding the core. 'der Kern' is the inedible, central seed.

Das Fruchtfleisch des Pfirsichs ist süß, aber Vorsicht vor dem Kern! (The peach's flesh is sweet, but beware of the pit!)

Both 'der Kern' and 'der Samen' can refer to a seed.

While 'der Kern' often specifically refers to the hard, central part of a fruit (like an apple or cherry pit), 'der Samen' is a more general term for any seed that can grow into a new plant. A 'Kern' can be a type of 'Samen'.

Ein Sonnenblumenkern ist ein Samen, aber nicht jeder Samen ist ein Kern im Sinne eines Obstkerns. (A sunflower seed is a seed, but not every seed is a core in the sense of a fruit pit.)

In some contexts, 'der Stein' can also mean a fruit pit.

'der Stein' is a general word for 'stone' or 'rock'. When used for fruit, it specifically refers to the pit of stone fruits (like peaches or cherries). 'der Kern' is more broadly applicable to the central part of various fruits and nuts.

Der Kirschkern wird auch Kirschstein genannt. (The cherry pit is also called a cherry stone.)

Both refer to a hard, inedible part inside something edible, leading to confusion.

'die Gräte' refers to a fish bone. 'der Kern' refers to the core of a fruit or nut.

Achtung vor den Gräten im Fisch! (Watch out for the bones in the fish!)
