An individual semantic feature constitutes one component of a word's intention, which is the inherent sense or concept evoked.

a direct specific meaning as distinct from an implied or associated idea

Something that is implicit is inferred - it is suggested by the way it is said. Implicit meaning can be harder to figure out than explicit meaning.

While each of these two words has several possible meanings, they are notably distinct from each other in all senses. Denotation is concerned with explicit meaning, and connotation tends to be concerned with implicit meaning.
