Surge

This is an abstract noun; something you cannot see, touch, hear, smell, or taste. These nouns represent concepts, ideas, or qualities that do not have a physical form and cannot be perceived through the senses.

For example, love can be felt, freedom can be experienced, and intelligence can be demonstrated, but none of these can be directly observed in a physical way. This type of noun covers all intangible elements, from emotions like joy and fear to complex concepts like justice and beauty. They form the conceptual world around us, allowing us to communicate about feelings, ideas, and attributes that are experienced internally or understood mentally.
