verträglich

Verträglich is a German adjective meaning compatible or well tolerated. It is used to describe how a substance, product, or interaction relates to another and to people. The core sense is that no significant conflict or adverse reaction occurs; it implies suitability for use with something else or for a group of users. The corresponding noun is Verträglichkeit, referring to tolerability or compatibility.

In medicine, a drug or treatment is described as gut verträglich when it causes few or mild side effects and is generally well tolerated by patients. The term is common in drug labeling and clinical descriptions, and it can also refer to the absence of harmful interactions with other medications or food.

In cosmetics and consumer products, hautverträglich or verträglich with sensitive skin is used to indicate skin compatibility and low irritancy. Labeling often emphasizes Verträglichkeit with different skin types or with other products.

In social and everyday language, verträglich can describe interpersonal relations: zwei Personen or Gruppen “vertragen sich gut” indicates they get along harmoniously, while "verträglich" can describe a temperament that is agreeable or non-confrontational.

Etymology: verträglich is formed with the prefix ver- and the stem tragen (to bear), giving the sense of something that can be borne or tolerated. The related noun Verträglichkeit covers tolerability and compatibility across contexts, including pharmacology, cosmetics, and nutrition.
