in order of masculine, feminine, neuter, plural

• nominative: der, die, das, die
• accusative: den, die, das, die
• dative: dem, der, dem, den
• genititive: des, der, des, der

which becomes:

• RESE
• NESE
• MRMN
• SRSR

in high school I pronounced this mnemonic as:

• resee
• nesee
• Mormon
• sir sir

My teacher didn’t like the “Mormon” bit, he wanted me to say “merman” but I found it easier to remember “Mormon” and his discomfort only made it stick better, lol.
