The word "simulation" traces back to the Latin simulare ("to imitate, copy"), derived from similis ("like, similar"). The morpheme simul preserves the core idea of likeness, while -ation transforms the verb into a noun denoting the process or result of imitation. Historically, it evolved through Old French (simulacion) before entering Middle English, retaining its focus on artificial replication. The term gained technical prominence in the 20th century with computer-based modeling.
