Any one of the languages that people have designed for specific purposes, such as representing
mathematical ideas or computer programs; all programming languages are this kind of languages.
formal language
Any one of the languages that people speak that evolved naturally.
natural language
An error that does not occur until the program has started to execute but that prevents the program
from continuing.
runtime error
An error in a program that makes it do something other than what the programmer intended.
Semantics error
The meaning of a program.
semantics
The structure of a program.

An error in a program that makes it impossible to parse — and therefore impossible to interpret.
syntax error
One of the basic elements of the syntactic structure of a program, analogous to a word in a natural
