What does dodecastyle mean?
Dodecastyle is a specialized term of classical architecture denoting a building or colonnade with twelve columns across its front. Formed from the Greek roots dōdeka ('twelve') and stylos ('column'), it belongs to a family of numerical terms — from tetrastyle to decastyle — used by architects and historians to classify porticoes and temple facades by column count. Because twelve columns make for an exceptionally broad frontage, the term is typically applied to monumental structures, most famously certain large Roman temples. In modern usage, dodecastyle appears almost exclusively in academic and architectural literature, functioning as either a noun ('a dodecastyle') or an adjective ('a dodecastyle portico'). For general readers, its value lies chiefly in illuminating how precisely classical builders described and standardized their designs.

Used almost exclusively in architectural history and classical scholarship.
(Of a building or portico) having twelve columns across its front.

Etymology of dodecastyle
Dodecastyle derives from the Greek dōdeka, meaning 'twelve', combined with stylos, meaning 'column'. The term entered English through Latin as part of the classical vocabulary of architecture, alongside related numerical forms such as tetrastyle (four columns), hexastyle (six), octastyle (eight), and decastyle (ten). These classifications were systematized in ancient architectural treatises, notably Vitruvius's De architectura, which described temple types by their frontal column counts.
