My native lanugage is Hindi, and I am not versed in English. I am reading a book and I came across the following paragraph:
Maybe most serious of all is when the fight-or-flight response becomes “kindled,” or sensitized, making the child much more easily and repeatedly startled. When this happens, the child pulls away from us.
I am not able to understand the above paragraph primarily because of the two words: Kindled, and sensitized. I searched for the meaning of these two words over the internet, but I couldn't see how these two words fit in the context of above paragraph. Can someone help me to understand the meaning of the above paragraph?
