The word "Laconical" derives from the word "Laconic", which comes from the Greek word "Lakōnikos". "Lakōnikos" refers to something or someone related to Laconia, an ancient region in southern Greece. The people of Laconia, known as the Spartans, were famously known for their brevity in speech and expression. Thus, "Laconic" came to describe a concise or terse style of communication. Consequently, "Laconical" is an adjective form of "Laconic" and describes something related or resembling this style.
