Use "clerestory" in a sentence
"I thought the term clerestory window was pronounced like cler-est-or-eee."
"The eastern part of the clerestory is a modern reproduction of that which superseded Rahere's; but, with this exception, the interior of the choir was probably much the same originally as it is"
"This applies only to the windows in the aisle; those in the triforium are of three lights, similar to those removed from the aisle; and those in the clerestory are the original Norman, just as on the north side."
