Etymology
The word 'vestibule' entered English in the early 17th century from Latin vestibulum, which referred to the forecourt or entrance of a Roman house. The Latin term's own origins are obscure but it is thought to possibly derive from an Italic root. The core semantic concept has always been an antechamber or transitional space. The diminutive force of the suffix, though now semantically bleached in English, originally reinforced the notion of it being a smaller, preliminary area leading to a larger main space. This logic of a connecting passageway was seamlessly extended from architecture to describe analogous anatomical structures in the 18th and 19th centuries.
