means The capacity to register and respond to feelings, stimuli, or situations with unusual acuteness — sometimes a gift, sometimes a raw nerve.

from From Latin sensitivus, 'capable of sensation,' built on sentire, 'to feel or perceive' — the same root that gives us sense, sentiment, and sentence (originally 'a way of feeling or thinking'). The word moved through medieval Latin into French and then English by the 1600s, first in a dry philosophical sense — describing organisms capable of sensation, as opposed to merely vegetative or mechanical ones. Only later did it soften into the emotional, interpersonal meaning we use now: someone who feels things keenly, for better or worse.
