rise (v.): 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; class I strong verb; past tense ras, past participle risen), from Proto-Germanic *us-risanan "to go up" (cognates: 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").

From c. 1200 as "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." Meaning "come into existence, originate; result (from)" is mid-13c. From early 14c. as "rebel, revolt;" also "occur, happen, come to pass; take place." Related to raise (v.). Related: Rose; risen.
see-saw (v.): also seesaw, "move up and down," 1712, from see-saw (n.). Related: See-sawed; see-sawing.
up (v.): 1550s, "to drive and catch (swans)," from up (adv.). Intransitive meaning "get up, rise to one's feet" (as in up and leave) is recorded from 1640s. Sense of "to move upward" is recorded from 1737. Meaning "increase" (as in up the price of oil) is attested from 1915. Compare Old English verb uppian "to rise up, swell." Related: Upped; upping. Upping block is attested from 1796.
valgus (adj.): deformity in which a bone or joint is twisted outward from the center of the body; form of club-foot, 1800, from Latin valgus "bandy-legged, bow-legged, having the legs bent outward." Said to be probably related to Sanskrit valgati "to move up and down," Old English wealcan "to roll, move to and fro" (see walk (v.)), perhaps on the notion of "go irregularly or to and fro" [Tucker]. "Yet the main characteristic of 'bow-legged' is the crookedness of the legs, not 'going up and down' or 'to and fro'" [de Vaan] and there are phonetic difficulties. A classical word used in a different sense in modern medicine; also see varus.
