The adjective sensory describes something relating to sensation — something that you feel with your physical senses. Sticking a knife into a toaster will give you a sensory experience, but so will smelling a rose. Stick with the rose.
Sensory comes from the Latin word sentire, meaning "to perceive, feel." Sampling your mom's blueberry pie is a sensory experience — you can smell it, you can taste it, and the crust has a really good texture. You may get sensory overload when you're in New York City because there's so much for your senses to take in. Sensory can also describe a nerve fiber, such as a sensory neuron, that carries impulses to the nerve centers in your body.
