Semantic Error

Definition of term

A semantic error in a program is an error where the meaning of some aspect of a program is nonsense.

Analogy

"Time is orange." is a natural language semantic error. Though the sentence is well formed, it is nonsense.

Example

In computer languages, similar errors can be made. For example a function may be declared to return an integer in one place on a program, and declared to return a complex data type in another.
