Haderlump - swearword for a good-for-nothing in torn clothing

However, the "Haderlump" was actually a rag collector who bought worn clothing and scraps of fabric (called "Hadern" or "Lumpen" in German), from the population and then sold them to paper mills. From the Middle Ages until the 18th century, scraps of linen, hemp or cotton were more or less the only available fibre raw material for paper production.

Incidentally, the word "Haderlump" is a tautology - two words that mean the same thing - similar to the expressions "former alumni" (alumni means those who are former members of an institution, school etc - so the word "former" is just saying it twice).

The rag collector belonged to the so-called "travelling people", a derogatory term that was often associated with criminality and dishonour.
