Post by Evan Kirshenbaumhob (hòb) noun
1. Chiefly British. A hobgoblin, a sprite, or an elf.
And I dimly recall "Hob" as a nickname for the devil.
According to MWCD10, this sense of "hob", which is the older of the
two, comes from Middle English "Hobbe", a nickname for Robert.
It would appear that "hobgoblin" is a retronym, as "hob" for the
goblin is dated to the fifteenth century, "hob" for the fireplace
insert is dated 1511, and "hobgoblin", for the older sense, is dated
1530.
John Ciardi has something interesting to add:
Hob A familiar dialect nickname for Robin Goodfellow, also called
Puck, a sprite more mischievous than evil. [XV < _(hob)goblin_.
But Hob was also a standard nickname for the once common given
name Robin.] "raise Hob" 1. Lit. To summon Robin Goodfellow (to
his mischief). 2. _Effective sense_. To act up. To play pranks.
"play Hob with" To spoil; to destroy. "Jean Borup keeps saying no,
which raises Hob with my fantasy life".
NOTE. In "A Midsummer Night's Dream," II. i. 32-41, the Fairy,
addressing Robin Goodfellow, sums him up:
Either I mistake your shape and seeming quite,
Or else you are that shrewd and knavish sprite
Called Robin Goodfellow: are you not he
That frights the maidens of the villagery;
Skim milk, and sometimes labour in the quern,
And bootless make the breathless housewife churn;
And sometimes make the drink to bear no barm;
Mislead night wanderers, laughing at their harm?
Those that Hobgoblin call you and sweet Puck,
You do their work, and they shall have good luck:
Are you not he?
("Quern," a hand mill for grinding grain; "barm," froth.)
