Throb
THROB, verb intransitive [perhaps allied to drive and to drub; at least its elements and signification coincide.] To beat, as the heart or pulse, with more than usual force or rapidity; to beat in consequence of agitation; to palpitate. The heart throbs with joy, desire of fear; the violent action of the heart is perceived by a throbbing pulse.
My heart throbs to know one thing.
We apply the word also the breast.
Here may his head live on my throbbing breast.
THROB, noun A beat or strong pulsation; a violent beating of the heart and arteries; a palpitation.
Thou talk'st like one who never felt
Th' impatient throbs and longings of a soul
That pants and reaches after distant good.
