What does decastyle mean?
Decastyle is a specialized term from classical architecture denoting a building or portico whose front is formed by a row of ten columns. The word derives from Greek roots meaning 'ten' and 'pillar', and it belongs to a family of architectural terms that classify temples by their column count, such as tetrastyle (four), hexastyle (six), and octastyle (eight). A decastyle facade was an imposing statement in the ancient world, since erecting ten massive columns demanded exceptional resources and ambition, so the term often implies grandeur on a monumental scale. Today it appears chiefly in archaeology, architectural history, and learned description of ancient temples, where precision about columnar arrangement matters. For general readers, it is a useful reminder of how Greek technical vocabulary continues to give English exact words for things otherwise describable only by lengthy paraphrase.
nounA classical building or portico having ten columns across its front; the word can also denote the row of ten columns itself.

Etymology of decastyle
Decastyle comes from the Greek elements deka-, meaning 'ten', and stylos, meaning 'pillar' or 'column'. It entered English as a term of classical architecture, likely by way of Latin or scholarly writing on ancient buildings, during the early modern period when antiquarian study of Greek and Roman ruins flourished. It shares its roots with related architectural terms such as peristyle ('surrounded by pillars') and hypostyle ('resting on pillars'), all built on stylos.
