English Synonyms and Antonyms

  1. radical

    The widely divergent senses in which the word radical is used, by which it can be at some time interchanged with any word in the above list, are all formed upon the one primary sense of having to do with or proceeding from the root (Latin radix); a radical difference is one that springs from the root, and is thus constitutional, essential, fundamental, organic, original; a radical change is one that does not stop at the surface, but reaches down to the very root, and is entire, thorough, total; since the majority find superficial treatment of any matter the easiest and most comfortable, radical measures, which strike at the root of evil or need, are apt to be looked upon as extreme.

    complete, constitutional, entire, essential, extreme, fundamental, ingrained, innate, native, natural, organic, original, perfect, positive, primitive, thorough, thoroughgoing, total

    conservative, inadequate, incomplete, moderate, palliative, partial, slight, superficial, tentative, trial

How to use radical in a sentence?

  1. Marco Rubio:

    Only America can convene Sunni forces from what I believe needs to be a combined Sunni force of Egyptians, Saudis, Jordanians, Sunnis in Iraq, Sunnis in Syria to confront a radical Sunni movement and defeat them militarily. They will need our help in convening it, but it doesn't involve a full-scale U.S. invasion of Iraq.

  2. Robin Simcox:

    Pathways out of extremism are very rarely instantaneous. It can take years for former extremists to fully disengage from this ideology. Expecting someone who was fighting alongside ISIS one day to be a legitimate ally in the fight against Islamist extremism the day after is an unrealistic expectation, the increasingly popular idea that we should not jail terrorists because that would only make them even more radical shows how utterly backwards this entire debate can become. Yes, prison radicalization does exist. However, the answer is to deal with the conditions that create prison radicalization – an inability to isolate charismatic Islamist recruiters, for example – not stop sending those who broke the law to prison.

  3. Avigdor Liberman:

    In truth, attempts to regulate the civilian possession of firearms have five political functions. They (1) increase citizen reliance on government and tolerance of increased police powers and abuse; (2) help prevent opposition to the government; (3) facilitate repressive action by government and its allies; (4) lessen the pressure for major or radical reform; and (5) can be selectively enforced against those perceived to be a threat to government.

  5. Martin Luther King Jr.:

    When you are right you cannot be too radical; when you are wrong, you cannot be too conservative.
