Synonyms 1. near, at hand. Imminent, Impending, Threatening all may carry the implication of menace, misfortune, disaster, but they do so in differing degrees. Imminent may portend evil: an imminent catastrophe, but also may mean simply “about to happen”: The merger is imminent. Impending has a weaker sense of immediacy and threat than imminent: Real tax relief legislation is impending, but it too may be used in situations portending disaster: impending social upheaval; to dread the impending investigation. Threatening almost always suggests ominous warning and menace: a threatening sky just before the tornado struck. 
Synonyms instigate, provoke, goad, spur, arouse, exhort; fire; induce. Incite, rouse, provoke, inflame are verbs meaning to goad or inspire an individual or a group to take some action or to express some feeling. Incite and rouse are similar in that, although they can imply in some contexts abrasive or inflammatory arousal of violent or uncontrolled behavior, neither necessarily does so. Incite means simply to induce activity, of whatever kind: incited to greater effort by encouragement; incited to riot. Rouse has an underlying sense of awakening: to rouse the apathetic soldiers to a determination to win; to rouse the inattentive public to an awareness of the danger. Provoke implies a sense of challenge or irritation along with arousal and often suggests a resultant anger or violence: provoked by scathing references to his accomplishments; to provoke a wave of resentment. Inflame, with its root sense to set afire, implies a resultant intensity and passion: to inflame a mob by fiery speeches; He was inflamed to rage by constant frustration.
Synonyms 1. deduce, reason, guess.
—Usage note Infer has been used to mean “to hint or suggest” since the 16th century by speakers and writers of unquestioned ability and eminence: The next speaker criticized the proposal, inferring that it was made solely to embarrass the government. Despite its long history, many 20th-century usage guides condemn the use, maintaining that the proper word for the intended sense is imply and that to use infer is to lose a valuable distinction between the two words.
Although the claimed distinction has probably existed chiefly in the pronouncements of usage guides, and although the use of infer to mean “to suggest” usually produces no ambiguity, the distinction too has a long history and is widely observed by many speakers and writers.

These adjectives mean existing in a person or thing from birth or origin. Something that is innate seems essential to the nature, character, or constitution: innate common sense.

6 Synonyms 1, 2. Irony, sarcasm, satire indicate mockery of something or someone. The essential feature of irony is the indirect presentation of a contradiction between an action or expression and the context in which it occurs. In the figure of speech, emphasis is placed on the opposition between the literal and intended meaning of a statement; one thing is said and its opposite implied, as in the comment, “Beautiful weather, isn't it?” made when it is raining or nasty. Ironic literature exploits, in addition to the rhetorical figure, such devices as character development, situation, and plot to stress the paradoxical nature of reality or the contrast between an ideal and actual condition, set of circumstances, etc., frequently in such a way as to stress the absurdity present in the contradiction between substance and form. Irony differs from sarcasm in greater subtlety and wit. In sarcasm ridicule or mockery is used harshly, often crudely and contemptuously, for destructive purposes. It may be used in an indirect manner, and have the form of irony, as in “What a fine musician you turned out to be!” or it may be used in the form of a direct statement, “You couldn't play one piece correctly if you had two assistants.” The distinctive quality of sarcasm is present in the spoken word and manifested chiefly by vocal inflection, whereas satire and irony, arising originally as literary and rhetorical forms, are exhibited in the organization or structuring of either language or literary material. Satire usually implies the use of irony or sarcasm for censorious or critical purposes and is often directed at public figures or institutions, conventional behavior, political situations, etc.
