weakens

Weakens is the third‑person singular present form of the verb “weaken,” meaning to make or become less strong, less forceful, or less effective. In physical contexts, weakening may refer to a reduction in structural integrity, such as the deterioration of materials due to corrosion, fatigue, or damage. In biology, it can describe the loss of physiological vigor, for example when an organism’s immune response is compromised by disease or malnutrition. Psychologically, the term is used for diminishment of mental resilience or confidence, as when stressors or negative feedback erode self‑esteem.

The verb is often employed in a causal construction (“X weakens Y”) to indicate the agent responsible for the reduction. For instance, “regular exercise weakens the risk of cardiovascular disease” conveys that exercise decreases the likelihood of the condition. The passive form (“Y is weakened by X”) places emphasis on the entity affected: “The fabric is weakened by prolonged exposure to sunlight.” Synonyms include diminish, impair, dilute, and sap, while antonyms encompass strengthen, reinforce, and fortify.

In technical literature, “weakens” may appear in discussions of algorithms, where a weakening of constraints leads to broader solution spaces, or in legal language, where certain provisions “weaken” the applicability of a statute. The term retains its core meaning across disciplines: a transition from a state of relative strength to one of reduced capacity.
