💡 Mnemonics for 'der Keim'

Article Mnemonic: Think of DERminating germs. 'Der' sounds a bit like the start of 'germinate'. It takes masculine strength (der) for a Keim to push through the soil.

Meaning Mnemonic: A Keim can cause a medical 'chime' (alarm sound) if it's a bad germ, or it's the tiny 'key' (sounds like Keim) that unlocks future growth (like a plant or an idea).

trägt Zukunft in sich, wunderbar.
Mal Pflanze zart, mal Virus klein,

entspringt dem Keim manch Lebenshauch.

(A little germ/seed, quite plain to see,
holds future in it, wonderfully.
Sometimes a plant, sometimes virus small,

In good things as in bad the same,
from the germ/seed springs life's breath or flame.)
