Bob is a group of short, mostly colloquial words of obscure origin that have become entangled in form and sense;[1][2] the dictionaries separate at least the verb “to move up and down”, the noun “a cluster, a short haircut”, and the slang “shilling”.[3][4][5]

bob1 move up and down
- Confidence
- Uncertain
- Formation
- Onomatopoeia
- First attested
- c. 1390
- From
- Middle English bobben
Etymology
It is inherited from Middle English bobben,[5][1] perhaps the same word as Middle English bobben “to strike, beat”, before 1325,[5][1] of a short, jerking or rebounding movement.[5][7] Etymonline connects it with bobben “to make a fool of, cheat”, perhaps from Old French bober “to mock”,[1] and the American Heritage and Merriam-Webster think it probably ultimately imitative.[8][9]
Earliest recorded meaning
“To move quickly up and down”: about 1390, in Chaucer's Canterbury Tales,[5] the late 14th century in Etymonline.[1]
Semantic evolution
The noun, a sudden jerk up and down, is from about 1550, the 1540s in Etymonline,[5][1] and a curtsy from the early 19th century.[4] Bobbing for apples or cherries, snatching with the mouth something hanging or floating, is recorded by 1799,[1] and to bob and weave, in boxing, by 1928.[1] In bell-ringing a bob is a kind of change in long peals, from the late 17th century.[4]

bob2 cluster, short hair
- Confidence
- Uncertain
- Formation
- Inherited
- First attested
- c. 1390
- Inherited from
- Middle English bobbe
Etymology
It is inherited from Middle English bobbe (“bunch, cluster of leaves or flowers”),[5][1] a northern word of uncertain origin,[5][1][7] perhaps Celtic, compare Irish baban “tassel, cluster” and Scottish Gaelic babag.[1][5][9]
Earliest recorded meaning
A bunch or cluster, as of leaves or flowers: probably about 1390, in Sir Gawain and the Green Knight,[5] about 1340 in the OED, chiefly northern,[10] the mid-14th century in Etymonline.[1]
Semantic evolution
Many of its later uses have in common the notion of a round, hanging mass:[1] the weight on a fishing line (1610s), a pendulum (1752) or a plumb line (1832).[1][10] Others imply shortness:[2] a horse's docked tail (1570s), a knot or bunch of hair (1680s, 1688),[1][5] and the bobtail, bobcat (1888) and bobsled (1839).[2][5] The verb “to cut short” is American, from 1822,[5] and “to cut a woman's hair short all round” from 1918,[5] when the fashion was seen as a sign of radicalism;[1] the noun for the haircut is from 1920 in Etymonline,[1] 1926 in Galsworthy's The Silver Spoon according to Barnhart.[5] The bobby pin is from 1936.[5]

bob3 shilling
- Confidence
- Unknown
- First attested
- 1789
Etymology
Its origin is unknown;[1][4][2] it does not seem to be related to the other bobs.[2] Merriam-Webster suggests the nickname Bob, for Robert.[9]
Earliest recorded meaning
A shilling, as British slang: 1789.[1][3]
Semantic evolution
After decimalization it was used for five new pence.[4] Bob-a-job was the former slogan of the Scout Association's fund-raising week.[4]
Timeline
Modern meaning
Noun
- (British slang) A shilling.
Usage notes
Bob's your uncle, said when something is easily done, uses the pet form of Robert; the suggestion that it refers to Lord Salisbury appointing his nephew Arthur Balfour in 1887 is doubtful, since the first records are from the 1930s.[2] A further obsolete bob, “to make a fool of”, came from Old French bober.[4][9]
