I have been seeing the abbreviation abwert. quite often, and it seems to be unique to an online dictionary I am using. There is no glossary for the abbreviations I can refer to, and I can't seem to find its meaning by googling it. See below for an example:
Kauz der Kauz SUBST
1. in verschiedenen Arten vorkommender, zu den Eulen gehörender Vogel
2. umg. abwert. seltsamer, sonderbarer Mann Er ist schon ein komischer Kauz.
I would appreciate if someone could enlighten me about what this means. Thank you in advance.
