+**Abstract concepts** are ideas that do not exist as tangible objects, but rather as mental constructs or qualities. They are understood through thought and generalization, encompassing notions like [Truth](/wiki/truth) or [Justice](/wiki/justice). These concepts form the bedrock of complex understanding and communication, existing independent of specific instances.
