Weib meaning and definition in german

Weib usually cannot be a neutral term for “woman” in contemporary German (for that see Frau). Nonetheless, it is still rather a current word and may be more or less pejorative depending on context. It is most often heard among men, notably in the plural, in which case it has macho ring to it, without being particularly abusive: Du weißt ja, wie die Weiber sind... − “Well, you know what women are like...”
In older German (well into the 19th century), Weib was a normal word for a woman, usually one of the “common people”, or someone's wife. This more neutral sense is still retained in many derived terms, particularly weiblich ‎(“female”).
