Dum.

Mute; silent; not speaking. I was dumb with silence; I held my peace. Psalm 39:2.

Destitute of the power of speech; unable to utter articulate sounds; as the dumb brutes. The asylum at Hartford in Connecticut was the first institution in America for teaching the deaf and dumb to read and write.

Mute; not using or accompanied with speech; as a dumb show; dumb signs. To strike dumb, is to confound; to astonish; to render silent by astonishment; or it may be, to deprive of the power of speech.

To silence.
