In common usage and linguistics, concision (also called conciseness, succinctness, terseness, brevity, or laconicism) 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.
For example, a sentence of "It is a fact that most arguments must try to convince readers, that is the audience, that the arguments are true." may be expressed more concisely as "Most arguments must demonstrate their truth to readers." – the observations that the statement is a fact and that readers are its audience are redundant, and it is unnecessary to repeat the word "arguments" in the sentence.
"Laconic" speech or writing refers to the pithy bluntness that the Laconian people of ancient Greece were reputedly known for.
In linguistic research, there have been approaches to analyze the level of succinctness of texts using frame semantics.
