"give a name to," originally "make a knight," from late Old English dubbian "knight by ceremonially striking with a sword" (11c.), a word perhaps borrowed from Old French aduber "equip with arms, adorn" (11c.) which is of uncertain origin, probably Germanic, but there are phonetic difficulties. Meaning "provided with a name" is from 1590s. Related: Dubbed; dubbing.
Also re-militarize, 1920, transitive, "to rearm a country or territory that had been demilitarized; equip again with military forces and defenses," originally of Soviet Russia, from re- "back, again" + militarize (v.) or perhaps based on earlier demilitarize (v.). Related: remilitarized; remilitarizing; remilitarization.
"normal rhythmic relaxation of the heart" (alternating with the systole), 1570s, from medical Latin diastole, from Greek diastole "drawing asunder, dilation," from diastellein, from dia "through; thoroughly, entirely" (see dia-) + stellein "to set in order, arrange, array, equip, make ready," from PIE *stel-yo-, suffixed form of root *stel- "to put, stand, put in order," with derivatives referring to a standing object or place.
