Writing principle of using few words
Concise
In common usage and linguistics, concision is a communication principle of eliminating redundancy, generally achieved by using as few words as possible in a sentence while preserving its meaning.
More generally, it is achieved through the omission of parts that impart information that was already given, that is obvious or that is irrelevant. Outside of linguistics, a message may be similarly "dense" in other forms of communication.
