As shared by Mark Toney an  Elfchen is an eleven-word poem written across five lines. It’s also called an “Elevenie.” Elf means “eleven” in German, and -chen at the end of a German word indicates diminutive size and endearment. So, an Elfchen is a little poem of eleven words in five lines, as follows: Line 1: One word; Line 2: Two words; Line 3: Three words; Line 4: Four words; Line 5: one word. Thanks Mark.
