What It Means: Mamucium, the Latin version of the Ancient Britons' Mamm, the breast-like hill, later Mancunium. Newton Heath, United's original home, is exactly what it sounds like, the new town on the heath between Manchester and Oldham.
Why It's There: the Roman fort of AD79, a small weaving town in one of England real swampy backwaters until the 18th century when it turned into Cottonopolis. Still arguing with Birmingham two centuries later about which was the world's first industrial city, and with Liverpool about everything. Then belatedly realised it was the home of the computer.
Why They're There: literally a pub team. Started in 1878 by workers at the Lancashire and Yorkshire Railway depot in Newton Heath, using the nearby Three Crowns as a changing room - and with wonderful irony all organised by a Scouser, Frederick Attock. Joined the League in 1892, became Manchester United in 1902 after nearly going bust.
The Field of Dreams: the Theatre of Dreams as we must call Old Trafford today, is a welcome change from the home of vicious gangs lurking in the alleyways off what's now Matt Busby Way in the 70's - not to mention some of the cafes, where germ warfare may well have been invented. Now one of the world's great multi-sport and multi-functional arenas. Opened in 1910, with Boro one of its first visitors, and setting the tone for the next century they lost 4-1. The previous, notoriously toxic ground, Bank Street, was next to a chemical works with 30 chimneys and hated by visiting players. Boro lost 4-0 on their debut there. And there was also a stint at Maine Road in the late 1940's after Old Trafford was bombed. It made no difference to Boro; it was just like playing City - they lost all three games.
When it all Began: January 1894 (FA Cup); December 1899 (league).
Local Heroes: Sir Alex, Sir Matt, Sir Bobby; George Best, Duncan Edwards, Eric Cantona, Denis Law, Bryan Robson.
Local Villains: City, naturally, and Liverpool. Even for Sir Alex, whose first team talk famously told the players they were going to knock Liverpool off their perch, although he inserted a few Govan adjectives before both.
High Point: European Cups in 1968, 1999 and 2008; 20 league titles, 11 FA Cups (and all three together in 1999); four League Cups, a Cup-Winners' Cup. Plus a Super Cup, a World Club Championship and its predecessor the Intercontinental Cup.
Low Point: finishing bottom in their first two seasons in the League; relegations in 1922, 1931, 1937 and 1974; losing their first 12 games in 1930; avoiding the Third Division by one point in 1934; the last four seasons. And of course the Munich air crash.
Boro Highs: in the league 5-3 (November 1921), 3-0 (January 1930); in cups (4-1 (January 1933), 1-0 (October 1973).
Boro Lows: in the league, 3-6 (September 1908), 0-4 (September 1900); in cups 0-4 (January 1894). And 1969-70, one of the two seasons when they've been put out both cups by the same team, especially considering United's incredible escape via a fluke goal in the FA Cup at Ayresome Park, and Bill Gates' broken jaw in the replay.
Hello to: Douglas McCorquodale (December 1899), John Brown (September 1900), Harry Kent (September 1908), Harry Harrison (October 1919), Billy Forrest (January 1930), Micky Burns (October 1978), Tony McMahon and Danny Graham (October 2004).
Goodbye to: Sammy Aitken (April 1910), Eddie Murphy - not that one - (September 1946); Tom Woodward (January 1951), Anthony Ormerod (January 2000), Gary Pallister (November 2000).
Hello and Goodbye to: David Gordon (September 1908), John Honeyman (October 1910)
Boro Hero: George Camsell (May 1931), all the goals in a 4-4 as United were relegated; Malcolm Smith (October 1974) scorer of the last cup winner there; Benni Carbone (March 2002), one-man perpetual motion machine - and set up Alen Boksic's winner; Tomas Mejias (October 2015) penalty shoot-out hero.
One For The Team: James Morrison (March 2007), who'd finally had enough of Ronaldo's antics in the first game and over-the-top showboating in the replay, so put him into orbit. Applauded from the field by Boro fans, almost canonised in Liverpool and lauded throughout the land, like Jarvis Cocker after mooning at Michael Jackson at the 1996 Brits.
Boro Villain: Jack Picken (April 1910) all the goals in 4-1 defeat; Jack Rowley (August 1951) hat-trick in 4-2 defeat. Mark Schwarzer (January 2000), a not unlike Victor Valdes at Burnley moment with David Beckham's free kick after Boro's 10 men had held out for 88 minutes with the goalkeeper unbeatable up to then.
Special Boro Villain: Cristiano Rolando, largely because of penalties and free-kicks, both won and taken, and consequent bookings, notably George Boateng; Roy Keane (October 1995), sent off for flattening Jamie Pollock, but not (January 2000) for chasing Andy D'Urso round the ground after he dared to award only the third penalty against United there in the Premier League.
Unexpected Item in Bagging Area: Brad Jones (May 2006) saved a Ruud van Nistelrooy penalty to earn a 0-0.
Boro Bogeyman: Juninho (January 2000) missed from the spot, as he did with his other two Boro penalties and all his free-kicks; Peter Schmeichel (March 1992), that breath-taking one-handed save from Willie Falconer's header in the League Cup semi-final.
Boro Bad Boy: Christian Ziege (January 2000), off for fouling David Beckham; Emmanuel Pogatetz (September 2008), off for tackle on Rodrigo Possibon; and of course James Morrison (March 2007).
Typical Boro: Ziege was the first Premier League player sent off this century; 1-0 (March 2002), after United had won 14 of their previous 16 games; 3-3 (May 1997) Gary Neville's first career goal after 117 games.
Nearly Boro: almost went bust (again) in 1931, with banks calling in their loans, crowds of less than 4,000, until saved by local businessman called Gibson.
Cultural Contribution: The computer, one of which has been pairing Boro with usually Blackburn or Everton at Christmas since 1968. The people who did it before then were from nearby Rossendale and they did the same - New Year 1903 at Goodison in Boro's first Division One season.
Omen Corner: Jose Mourinho watched two Boro games last season as Aitor Karanka's guest after being sacked by Chelsea - and saw two wins at Brighton and Fulham.
Your Boys Took One Hell of a Beating: stick a pin in a map of any continent (even Antarctica - there's probably a penguin MUFC supporters' Club) and you'll find more United replica kits than there were Boro fans at the Port Vale game in 1986. Nearly 400 "famous" United fans are listed by Pride of Manchester, though even Mail Online would struggle with some of them. One, author Ian Hough (who they certainly would struggle with as he rarely appears in a swimsuit "showing his well-honed pecs") chose a Boro game for his first visit to Old Trafford in October 1978. Naturally Boro lost, 3-2, but instead of being inspired by Micky Burns' goalscoring debut he came up with Perry Boys, a tale of hooligans in Fred Perry polo shirts. If he'd come to the return he'd have seen various Casuals and Joeys slouching round Ayresome Park, but all put into the sartorial shade by David Hodgson's jacket/shirt combinations, like a flare-off at Wilton with a moustache.
