My answer is I don't know how the word, div or divvy originated.

I believe I first heard it being used on the BBC1 sitcom, Porridge, (1974-1977) starring Ronnie Barker. The television comedy was centred on a petty criminal, Norman Stanley Fletcher, sentenced to serve a five-year stretch at HMP Prison Slade. Perhaps due to its huge success and oft repeated shows the expression, div or divvy, spread throughout the UK. That's my theory; the book, Porridge The Complete Scripts with all the scripts taken from the show is in print, but unfortunately, there isn't an e-book version, so I can't confirm my instinct.

Nevertheless on the Internet theories abound as to its origin. Here are among the best I found.

From A Dictionary of Slang and Unconventional English By Eric Partridge

• The excerpt suggests that the term divvy was used in borstals; a type of youth prison in the United Kingdom, and detention centres.

• Perhaps div is a deviation of the words, dippy or diwified.

• Alternatively an old slang term, meaning someone who guesses right about something without being an expert. (If you aren't an expert you must be either ignorant or a fool?)

• Derived from divot, a clump of turf. And clump is just another expression for an idiot or foolish person.

From a Q&A Internet forum I found this nugget of information:

1. A person that is a bit stupid, a waster or unemployed. The word Div/Divvy comes from a shortening of the Unemployment Dividend of the 1950's.

2. A Northern English word from the mining community's use of different types of lamp whilst underground. The dangerous lamp nicknamed Davy Lamp was not very safe and tended to explode, this was replaced with the Geordie Lamp which was a lot safer. Colliers that went underground using a Davy Lamp soon started being called Divvies.

In the so-far-as-I could-tell excellent website, Inky Fool, in the comments section:

I remember kids being referred to as "divot" back in the late 60s, early 70s. Div was a later shortened version.

and

I, too, remember divot and div from the late sixties and early seventies in South Lincolnshire. I assumed that a divot was a variant on the theme of clod.

Which both give further evidence or credence to the "divot digger" theory.

And finally but not least, a divvy officer, a slang term for a petty officer of the navy.

Div and divvi appear in Romani in Britain: The Afterlife of a Language (2010), by Yaron Matras, linguist at the University of Manchester:

fool n. div, divvi, divya ER divjo 'wild'

ER is European Romani. Here's some example corpus uses from the University of Manchester's Angloromani Dictionary:

he's a divvi

kek, don't mang that divvi, nash on

Being of the right age and birthplace I always assumed it was short for a person who was divergent from the name caller. Could mean anything the caller wanted and that was the most annoying thing about being called a divi.

Believed to originate from British military personel in Northern Island in the late 60's early 70's, as a derogatory term relating to people living in the Divvies flats area.

In the British TV series "Lovejoy", the antique dealer (Lovejoy) was called a divvy because of his intuitive recognition of valuable and genuine objects - based on "diviner".

I don't know its origin but definitely remember using the word at schoolfrom 1958 on (south west London). A generally used term for someone who's a bit stupid/thick/etc.

I have lately discovered another possibility for the derivation of this word. It seems that in the mines around Newcastle there used to be an inferior type of safety lamp known as a divvy, a name which stuck to the users as only a divvy would risk going underground with one:-

Another word, divvie or divvy ("idiot"), seems to come from the Co-op dividend, or from the two Davy lamps (the more explosive Scotch Davy used in 1850, commission disapproved of its use in 1886 (inventor not known), nicknamed Scotch Davy probably given by miners after the Davy lamp was made perhaps by north east miners who used the Stephenson Lamp), and the later better designed Davy designed by Humphry Davy also called the Divvy.) As in a north east miner saying 'Marra, ye keep way from me if ye usin a divvy.' It seems the word divvie then translated to daft lad/lass. Perhaps coming from the fact one would be seen as foolish going down a mine with a Scotch Divvy when there are safer lamps available, like the Geordie, or the Davy. [Wikipedia entry on Geordie]
