Why was "tantrum" trending last week?
early 14c., lettorne, lettron, from Old French letron, from Medieval Latin lectrinum, from Late Latin lectrum "lectern," from root of Latin legere "to read" (see lecture (n.)). Half-re-Latinized in English in 15c.
originally a pedestal-based reading desk with a slanted top used for supporting liturgical books-such as Bibles, missals, and breviaries at religious services; later, a stand that supports a speaker's books and notes. In early Christian times, lecterns, then known as ambos, were incorporated into the structure of the sanctuary-one on the north side of the choir for reading the Epistle, the other at the south for reading the Gospel
