from glaver (to flatter, to deceive with flattery) + -y;

EXAMPLE
“… But I staie my selfe and assure you of this, that in al crations and speeches, in all pleas, and actions, for and against any man amongst them, honest plainenesse was euer an argument of fauour and succour, and holowe smoothing glauerie a note of reprooch and an argument to perswade the contrarie. Nowe therefore let vs gather vppe all these againe together, and if heathens hate it, Christians loath it, and the God of life and death abhor it, what strength should anie cause in the earth haue to tempt you vnto it? …”
From: A Briefe Conference betwixt Mans Frailtie and Faith
