arise v.

prefix or inseparable particle, a conglomerate of various Germanic and Latin elements.

In words derived from Old English, it commonly represents Old English an "on, in, into" (see on (prep.)), as in alive, above, asleep, aback, abroad, afoot, ashore, ahead, abed, aside, obsolete arank "in rank and file," etc., forming adjectives and adverbs from nouns, with the notion "in, at; engaged in." In this use it is identical to a (2).

It also can represent Middle English of (prep.) "off, from," as in anew, afresh, akin, abreast. Or it can be a reduced form of the Old English past participle prefix ge-, as in aware.

Or it can be the Old English intensive a-, originally ar- (cognate with German er- and probably implying originally "motion away from"), as in abide, arise, awake, ashamed, marking a verb as momentary, a single event. Such words sometimes were refashioned in early modern English as though the prefix were Latin (accursed, allay, affright are examples).

In words from Romanic languages, often it represents reduced forms of Latin ad "to, toward; for" (see ad-), or ab "from, away, off" (see ab-); both of which by about 7c. had been reduced to a in the ancestor of Old French. In a few cases it represents Latin ex.

[I]t naturally happened that all these a- prefixes were at length confusedly lumped together in idea, and the resultant a- looked upon as vaguely intensive, rhetorical, euphonic, or even archaic, and wholly otiose. [OED]

Middle English risen, from Old English risan "to rise from sleep, get out of bed; stand up, rise to one's feet; get up from table; rise together; be fit, be proper" (typically gerisan, arisan; a I strong verb; past tense ras, past participle risen), from Proto-Germanic *us-rīsanan "to go up" (source also of Old Norse risa, Old Saxon risan, Old Frisian risa, "to rise; arise, happen," Gothic urreisan "to rise," Old High German risan "to rise, flow," German reisen "to travel," originally "to rise for a journey"). OED writes, "No related terms have been traced outside of Teutonic"; Boutkan suggests an origin in a lost European substrate language.

From late 12c. as "to rise from the dead," also "rebel, revolt, stand up in opposition." It is attested from c. 1200 in the senses of "move from a lower to a higher position, move upward; increase in number or amount; rise in fortune, prosper; become prominent;" also, of heavenly bodies, "appear above the horizon." To rise and shine "get up, get out of bed" is by 1916 (earlier it was a religious expression). Of seas, rivers, etc., "increase in height," c. 1300.

The meaning "come into existence, originate; result (from)" is by mid-13c. From early 14c. as "occur, happen, come to pass; take place." From 1540s of sound, "ascend in pitch." Also from 1540s of dough. It seems not to have been used of heat or temperature in Middle English; that sense may have developed from the use of the verb in reference to the behavior of fluid in a thermometer or barometer (1650s). Related to raise (v.). Related: Rose; risen.
