Haywire is wire used to bind bales of hay, and can also refer to something that’s roughly-made, erratic or uncontrollable. How are these meanings related? Let’s find out in this Adventure in Etymology.
As a noun, haywire [ˈheɪ.waɪ.ə(ɹ) / ˈheɪ.waɪɚ] means wire used for binding bales of hay, straw or grass, and is also known as bale wire, baling wire, farm wire or soft wire.
As an adjective, haywire means roughly-made, unsophisticated, decrepit, or behaviorally erratic or uncontrollable, especially when referring to machines and mechanical processes.
As a verb, to haywire means to attach or fix with haywire, and to go haywire means to become wildly confused, out of control, or mentally unbalanced. [source].
Originally haywire meant likely to become tangled unpredictably or unusably, or fall apart, as if bound by the soft springy wire used to bind hay bales. This usage comes from lumber camps in New England in 1905, when a haywire outfit was a company that patched up machinery temporarily using haywire rather than fixed it properly [source].
The expression to go haywire, which first appeared in writing in the 1920s, represents something held together or repaired with haywire falling apart or behaving unpredicatbly, or something that has gone wrong or is no good. As haywire tends to whip itself into wild and unruly tangles when cut, this meaning makes sense [source].
