Not too sure if this qualifies as a 'word of the day' - it's actually three words (and in Latin):
Part 2: June of 1958 Chapter 9 Cleaning Up (from the book "It")
"Apparebat eidolon senex" - Pliny
'There was an inscription on the stone birdbath. Stan read it but did not understand it - the only Latin he understood was the genus names in his bird classification book'
meaning is a phantom appeared in the form of an old man
Really good book - it's from 1986 and I do not know how I missed reading this the first time around when I was reading Stephen King books way back when
