what do impulsive mean?
Impulsive means acting without thinking.
The child was impulsive when he kicked his sister.
thanks very much ms. sue :) that mean the same thing as spontaneous?
Yes, they are very close in meaning.
Impulsive tends to be negative -- as my example shows. Spontaneous tends to be positive.
Example: The students broke into spontaneous applause when heroine walked on the stage.
