Usage tips
Compound word
The word consists of 'Morgen' (morning) and 'Stern' (star). This compound literally describes a star that is visible in the morning, which leads directly to the astronomical meaning.
EXAMPLE
Der Abendstern ist derselbe Planet wie der Morgenstern, nur am Abendhimmel.
The evening star is the same planet as the morning star, just in the evening sky.
Context clue
The word has two very different meanings. The context makes clear what is meant: if it is about the sky and planets, Venus is meant. If it is about knights, weapons, or the Middle Ages, the striking weapon is meant.
EXAMPLE
Am klaren Winterhimmel leuchtete der Morgenstern besonders hell.
In the clear winter sky, the morning star shone especially brightly.
Origin of the weapon meaning
The name of the weapon as 'Morgenstern' (morning star) is a metaphor. The spiked ball resembles a brightly shining star with its rays.
EXAMPLE
Die Waffe war gefürchtet, denn ein Schlag mit dem Morgenstern konnte selbst eine Rüstung zerbrechen.
The weapon was feared, because a blow with the morning star could even break armor.

Morgenstern vs Keule
leg / club
'der Morgenstern' and 'die Keule' can both refer to a striking weapon. 'Keule' is the more general word: it is a heavy stick that is thicker at the end and can serve as a weapon or tool. 'Morgenstern' is more specific and means a medieval weapon with a spiked ball at the end. The words can be confused because both occur in the area of old weapons. If you are only talking about a simple heavy striking weapon, 'Keule' fits better. If the spikes and the special shape are important, 'Morgenstern' is more precise.
