Old English risan "to rise, rise from sleep, get out of bed; stand up, rise to one's feet; get up from table; rise together; be fit, be proper" (usually arisan; a class 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, Gothic urreisan "to rise," Old High German risan "to rise, flow," German reisen "to travel," originally "to rise for a journey").
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 "rise from the dead." The meaning "come into existence, originate; result (from)" is by mid-13c. From early 14c. as "rebel, revolt;" also "occur, happen, come to pass; take place." Related to raise (v.). Related: Rose; risen.
