English Synonyms and Antonyms

  1. efficacy

    Power is the most general term of this group, including every quality, property, or faculty by which any change, effect, or result is, or may be, produced; as, the power of the legislature to enact laws, or of the executive to enforce them; the power of an acid to corrode a metal; the power of a polished surface to reflect light. Ability is nearly coextensive with power, but does not reach the positiveness and vigor that may be included in the meaning of power, ability often implying latent, as distinguished from active power; we speak of an exertion of power, but not of an exertion of ability. Power and ability include capacity, which is power to receive; but ability is often distinguished from capacity, as power that may be manifested in doing, as capacity is in receiving; one may have great capacity for acquiring knowledge, and yet not possess ability to teach. Efficiency is active power to effect a definite result, the power that actually does, as distinguished from that which may do. Competency is equal to the occasion, readiness prompt for the occasion. Faculty is an inherent quality of mind or body; talent, some special mental ability. Dexterity and skill are readiness and facility in action, having a special end; talent is innate, dexterity and skill are largely acquired. Our abilities include our natural capacity, faculties, and talents, with all the dexterity, skill, and readiness that can be acquired. Efficacy is the power to produce an intended effect as shown in the production of it; as, the efficacy of a drug. Efficiency is effectual agency, competent power; efficiency is applied in mechanics as denoting the ratio of the effect produced to the power expended in producing it; but this word is chiefly used of intelligent agents as denoting the quality that brings all one's power to bear promptly and to the best purpose on the thing to be done. Compare ADDRESS; DEXTERITY; SKILFUL.

    Synonyms:
    ability, aptitude, capability, capacity, cleverness, cogency, competency, dexterity, efficiency, energy, expertness, faculty, force, might, power, qualification, readiness, skill, strength, susceptibility, talent

    Antonyms:
    awkwardness, dulness, feebleness, helplessness, imbecility, impotence, inability, inaptitude, incapacity, incompetence, inefficiency, maladroitness, stupidity, unskilfulness, weakness

How to use efficacy in a sentence?

  1. Anuj Somany:

    Academic literacy & meritocracy are tertiary; competency & work efficacy are secondary; primary traits required usually are sycophancy & skulduggery/hypocrisy for an employee to rise through the ranks in the private sector corporate hierarchy.

  2. Paul Offit:

    I think from the standpoint of the public, it really shouldn't matter, it's been given to half of the American population. We have more than 300 million doses out there. This is far from experimental. We have a tremendous safety and efficacy portfolio on these vaccines -- I mean, it's more than most licensed products that are out there now.

  3. James Maddux:

    Exercise can be a mental distraction from worrisome thoughts. We also know that being out in nature generally enhances our sense of well-being, so exercise that takes place outdoors, such as skiing in this study, should be especially helpful, engaging in a period of exercise can lead to a sense of accomplishment and a greater sense of self-efficacy( or self-confidence) that can lead to lower anxiety.

  4. Michael Springborn:

    This suggests that efforts to utilize social distancing to mitigate disease spread may have a limited window of efficacy.

  5. Scott Nathan:

    Im not anti-vaccine. On the contrary, I get my flu shot every season and recently got my shingles vaccine. I dont have enough information yet to feel safe, i wont be first, but if the research and efficacy checks out, I probably wont wait more than a few months.
