ante-chapel
A term used in the Universities for the outer part at the west end of a chapel. It would form the transept of a cruciform church were a nave added, as was evidently intended at Merton College, Oxford. The plan was followed by Wykeham in New College, and Waynflete in Magdalen, and hence became a common feature in a collegiate chapel, both in Oxford and Cambridge. (Parker, 1896)
