Synonyms: spontaneous, impulsive, instinctive, involuntary, automatic
These adjectives mean acting, reacting, or happening without apparent forethought or prompting. Spontaneous applies to what arises naturally rather than resulting from external constraint or stimulus: "The highest and best form of efficiency is the spontaneous cooperation of a free people" (Woodrow Wilson).
Impulsive refers to the operation of a sudden urge or feeling not governed by reason: Buying a car was an impulsive act that he immediately regretted.
Instinctive implies behavior that is a natural consequence of membership in a species. The term also applies to what reflects or comes about as a result of a natural inclination or innate impulse: Helping people in an emergency seems as instinctive as breathing.
Involuntary refers to what is not subject to the control of the will: "People drew in their breath with involuntary surprise and suspense" (Harriet Beecher Stowe).
