die Schwester, -n

The German word "Schwester" is a noun that means "sister." It directly correlates to a female sibling. Additionally, in medical or professional contexts, "Schwester" can also refer to a nurse, specifically a female nurse, though this use is somewhat dated and less common in contemporary usage, where "Pfleger" or "Pflegekraft" (for both male and female nurses) are used.

Words with a similar familial meaning include "Bruder" (brother), while for the professional context, similar words include "Krankenschwester" (nurse), "Pflegerin" (female caregiver), or just "Pfleger" as previously noted.

The usage of "Schwester" for a nurse often correlates with the increased responsibility of nurses for caregiving, akin to a familial or protective role, typically associated with siblings in a close family context. However, this traditional term is becoming less frequent due to modern shifts toward gender-neutral professional titles.
