• 🔺 As a shape: A wedge-like shape or formation. For example, one might speak of a 'Keil Gänse' (wedge of geese) flying in a V-formation.

🛠️ Application and Context

The use of der Keil heavily depends on the context:

• Crafts/Technology: Here, der Keil is a concrete tool (Spaltkeil - splitting wedge, Treibkeil - driving wedge, Bremskeil - brake wedge/chock). One 'treibt einen Keil ein' (drives a wedge in) or 'setzt einen Keil an' (places a wedge).
• Describing Shapes: People talk about things being 'keilförmig' (wedge-shaped) or a 'Keil' of birds/airplanes. A slice of cake or pie can also be called a Keil (although 'Stück' - piece - is more common).
• Interpersonal Relationships: Here, der Keil metaphorically represents disagreement or division. The idiom 'einen Keil zwischen jemanden treiben' (to drive a wedge between someone) is very common.

⚠️ There's little risk of confusion (Verwechslungsgefahr) as the contexts are usually clear. The basic idea of a tapering shape that separates or spreads something is common to all meanings.

📜 Poem about the 'Keil'

Ein kleiner Keil, oft unscheinbar,
aus Holz, Metall, ganz wunderbar.
Er spaltet Holz mit Kraft und Druck,
ein nützlich Ding, Stück für Stück.

Doch treibt man ihn ins Herz hinein,
bringt er nur Zwietracht, Schmerz und Pein.
So nutz ihn weise, dieses Teil,
den scharfen, starken, festen Keil.

Translation:
A little wedge (Keil), often inconspicuous,
of wood, metal, quite wonderful.
It splits wood with force and pressure,
a useful thing, piece by piece.

But if driven into the heart,
it brings only discord, pain, and smart.
So use it wisely, this part,
the sharp, strong, sturdy wedge (Keil).
