Are there any mnemonic songs for Ancient Greek (particularly attic) endings?

Answer 1

I learned to memorize the first declension plurals by repeated "Dionysius," pronounced a bit awkwardly:

DIE - captures the nominative plural αι ending (pronounced like "eye")

ON - Captures the genitive plural ων (pronounced like "own")

ICE - Captures the dative plural αις (pronounced like "ice" with the first part like "aisle")

AS - captures the accusative ας (pronounced like the plural of "ah," ending like "Oz," where the Wizard lives)
