pew: [14] Historically, pew and podium are the same word. Both go back ultimately to Greek pódion ‘small foot, base’, a diminutive form of poús ‘foot’ (a distant relative of English foot). This passed into Latin as podium ‘raised place, balcony’, acquired directly by English as podium [18]. Its plural podia passed into English via Old French puie ‘raised seat, balcony’ as pew.

This was originally used for a sort of raised enclosure in a church, court, etc. rather like a pulpit or dock; then for an enclosure in a church set aside for particular people to sit in (now known as a box pew); and finally (in the 17th century) for a church bench.
