pulse
pulse: English has two separate words pulse. The older, ‘seeds of beans, lentils, etc’ [13], comes via Old French pols from Latin puls ‘thick gruel (often made from beans and the like)’. This was a relative of Latin pollen ‘flour’ (source of English pollen) and Latin pulvis ‘powder’ (source of English powder and pulverize).Its plural pultes has given English poultice [16]. Pulse ‘beat of the blood’ [14], comes via Old French pouls from Latin pulsus ‘beating’, a noun use of the past participle of pellere ‘drive, beat’ (source of English appeal, compel [14], dispel [17], expel [14], propel [15], and repel [15]). The derivative pulsāre gave English pulsate [18], and also push.=> pollen, poultice, powder, pulverize; appeal, compel, dispel, expel, propel, pulsate, push, repel
pulse (n.1)
"a throb, a beat," early 14c., from Old French pous, pulse (late 12c., Modern French pouls) and directly from Latin pulsus (in pulsus venarum "beating from the blood in the veins"), past participle of pellere "to push, drive," from PIE *pel- (6) "to thrust, strike, drive" (cognates: Greek pallein "to wield, brandish, swing," pelemizein "to shake, cause to tremble"). Extended usages from 16c. Figurative use for "life, vitality, essential energy" is from 1530s.
pulse (v.)
"to beat, throb," early 15c., from pulse (n.1) or else from Latin pulsare "to beat, throb," and in part from French. Related: Pulsed; pulsing.
pulse (n.2)
"peas, beans, lentils," late 13c., from Old French pouls, pols and directly from Latin puls "thick gruel, porridge, mush," probably via Etruscan, from Greek poltos "porridge" made from flour, from PIE *pel- (1) "dust, flour" (see pollen; also compare poultice).
