If something goes haywire, it means it works erratically, in a crazy way or doesn’t work at all. We often use it when we’re talking about technology. That might make you think the ‘wire’ of ‘haywire’ is something to do with power-type wires (that’s the official technical term), but you would in fact be wrong. ‘Haywire’ actually has a much older meaning to do with… wait for it… hay.
Well, I didn’t say it was exciting.
People who deal with hay (farmers, I guess?) use baling wire – a thin, flexible metal wire – to bind together (you’ve guessed it) bales of hay. It’s a bit like duct tape, in that it’s used for all different types of quick and dirty repairs (see ‘The Martian’ by Andy Weir – and the Matt Damon-starring film – for the wonders of duct tape: ‘Yes, of course duct tape works in a near-vacuum. Duct tape works anywhere. Duct tape is magic and should be worshiped.’ I wholeheartedly agree). Some of the repairs baling wire is used for include ‘wiring gates shut, mending a fence, holding rickety machinery together and stuff like that’. This led to the expression ‘haywire outfit’, which appeared around the turn of the century. It referred to New England logging camps which used cheap temporary fixes (often involving baling wire) for repairing equipment, rather than doing it properly. Eventually the word ‘haywire’ came to describe anything that was flimsy or patched together, and then for attempts to fix things that went wrong.
Unlike duct tape, hay wire also has a reputation for being tricky to manage. That’s because, much like Christmas lights, wired headphones and my jewellery, it can get itself in a complete tangle without any outside intervention. It was probably this that led to ‘haywire’ getting the meaning of ‘crazy’ or ‘out of control’.
