(Playing around with English morphology and male masturbation, so not to everyone’s taste)
It all started with a chance encounter with an ad for Jackery portable power stations, like this one:
Given the orientation of my imagination, I was immediately taken to the idea of jackery ‘male masturbation, jacking off’, at places especially devoted to the practice, jackeries (aka jack-off / jerk-off / JO clubs). Clearly not what the Jackery Company had in mind, but where did they get their name?
From the “get to know Jackery” page on the company’s website:
Jackery was established in 2012 and co-founded by a former Apple senior engineer and a CEO called Z Sun, a pioneer in the field of Li-battery technology. The original founder developed a battery jacket for the Apple iPhone, which is where the name Jackery comes from.
… Jackery makes portable power stations, solar panels, solar generators, and accessories for the outdoor and mobile market, but they are best known for their portable power stations.
So Jackery has the derivational suffix –ery (denoting ‘a place where some occupation, trade, or activity is carried on’) attached to an abbreviated form of jacket, referring to one of the company’s first products.
The details of words with the the noun-forming derivational suffix –ery are not at all straightforward, full of oddities of history; it’s not a particularly productive suffix. But there’s enough there that you can play with it.
On to this interesting messiness in some detail, and moving from battery jackets to male masturbation.
