A flat board or molding that covers the ends of roof rafters and supports the bottom edge of roof tiles or gutters.
From Latin 'fascia,' meaning 'band' or 'bandage,' originally describing the strips of cloth used to wrap wounds or bind things together. Roman architects borrowed this medical term for the horizontal bands that 'wrapped around' buildings as decorative or structural elements. The same root gave us 'fascist' (from the Roman 'fasces' — bundles of rods bound together as a symbol of authority) and the medical term for connective tissue that 'binds' muscles.
Your house trim shares its name with political movements and medical bandages! Romans used the same word for wrapping wounds, binding bundles of sticks (the symbol of government power), and the decorative 'bands' around buildings. So when you paint your fascia boards, you're literally working on your house's 'bandages.'
