loppan

Loppan is a Swedish informal term that can refer to several different things, most commonly a flea. In this context, it is often used in a playful or affectionate way, particularly when referring to small children who might be described as "jumpy" or full of energy, much like a flea. The word can also be used to describe a small, troublesome insect in general.

Beyond its literal meaning, "Loppan" is also the name of a popular children's book character created by Swedish author Viveca Ljung. Loppan is a small, energetic, and somewhat mischievous dog. The books follow her adventures and often teach simple life lessons. The character has been widely recognized and enjoyed by generations of Swedish children.

In a more technical or colloquial sense, "loppan" can sometimes be used to describe a small, often second-hand, item or a bargain found in a flea market. This usage draws a parallel to the nature of fleas being small and sometimes found unexpectedly. The term generally carries a lighthearted and familiar connotation, rarely being used in a formal or negative context.
