abgeschwächt

Abgeschwächt is a German adjective derived from the verb abschwächen, meaning to weaken or attenuate. It describes something that has been reduced in strength, intensity, or potency, or that has been made less strong through processing, mitigation, or natural effects. The term is used across many domains, including everyday language, science, medicine and law.

In science and everyday usage, abgeschwächt can refer to signals, stimuli or effects that are diminished in amplitude or impact, such as a abgeschwächter Lichtpegel, a abgeschwächter Klang oder ein abgeschwächtes Phänomen. In biology and medicine, it is common in relation to attenuated pathogens or vaccines, for example abgeschwächte Viren or abgeschwächtes, lebendes Vakzin, which are designed to provoke immunity with reduced pathogenicity. The concept also appears in discussions of reduced efficacy or softened effects, as in einer abgeschwächten Form von etwas.

Grammatically, abgeschwächt is the past participle of abschwächen and functions as an adjective. With definite articles or in declined form, it takes endings according to gender, number and case, for example der abgeschwächte Reiz, eine abgeschwächte Form, das abgeschwächte Signal. The term is widely used in formal and neutral descriptive contexts to indicate a diminished strength or scope.
