Brewer's: Proclaim on the Housetop
To proclaim or make known to everyone; to blab in public. Dr. Jahn says that the ancient Jews “ascended their roofs to announce anything to the multitude, to pray to God, and to perform sacrifices” (Matt. x. 27).
“No secret can escape being proclaimed from the housetop.” —London Review.
Proclivity His proclivities are all evil. His tendencies or propensities have a wrong bias. The word means downhill tendency. (Latin, proclivis.)
