pullover adj.

c. 1300 (mid-13c. in surnames), "to move or try to move forcibly by pulling, to drag forcibly or with effort," from Old English pullian "to pluck off (wool), to draw out," a word of unknown origin, perhaps related to Low German pulen "remove the shell or husk," Frisian pûlje "to shell, husk," Middle Dutch polen "to peel, strip," Icelandic pula "work hard." Related: Pulled; pulling.

From early 14c. as "to pick, pull off, gather by hand" (fruit, flowers, berries, leaves, petals, etc.); mid-14c. as "to extract, uproot" (of teeth, weeds, etc.).

Sense of "to draw (to oneself), attract" is from c. 1400; sense of "to pluck at with the fingers" is from c. 1400; meaning "tear to pieces" is mid-15c. By late 16c. it had replaced draw (v.) in these senses. From mid-14c. as "to deprive (someone of something)."

To pull (someone's) chain in the figurative sense is from 1974, perhaps on the notion of a captive animal; the expression was also used for "to contact" (someone), on the notion of the chain that operates a signaling mechanism. To pull (someone's) leg is from 1882, perhaps on notion of "playfully tripping" (compare pull the long bow "exaggerate," 1830, and pulling someone's leg also sometimes was described as a way to awaken a sleeping person in a railway compartment, ship's berth, etc.). Thornton's "American Glossary" (1912) has pull (n.) "a jest" (to have a pull at (someone)), which it identifies as "local" and illustrates with an example from the Massachusetts Spy of May 21, 1817, which identifies it as "a Georgian phrase."

Old English ofer "beyond; above, in place or position higher than; upon; in; across, past; more than; on high," from Proto-Germanic *uberi (source also of Old Saxon obar, Old Frisian over, Old Norse yfir, Old High German ubar, German über, Gothic ufar "over, above"), from PIE root *uper "over."

As an adjective from Old English uffera. The senses of "past, done,  finished; through the whole extent, from beginning to end" are attested from late 14c. The sense of "so as to cover the whole surface" is from c. 1400. Meaning "leaning forward and down" is from 1540s. The meaning "recovered from" is from 1929. In radio communication, it is used to indicate the speaker has finished speaking (1926).

Above expresses greater elevation, but not necessarily in or near a perpendicular direction; over expresses perpendicularity or something near it: thus, one cloud may be above another, without being over it. Over often implies motion or extension where above would not; hence the difference in sense of the flying of a bird over or above a house, the hanging of a branch over or above a wall. In such uses over seems to represent greater nearness. [Century Dictionary]

Phrase over and above (mid-15c.) is pleonastic, for emphasis. Adjective phrase over-the-counter is attested from 1875, originally of stocks and shares. To be (someone) all over "be exactly what one expects of (someone)" is by 1721.
