Why Do We Call Food 'Grub'?

(Author's warning No. 1: If you're reading this column while eating breakfast, you might want to move on to the comics page.)

Watching contestants on reality TV swallow fat, writhing yellow grubs raises several icky entomological questions, including: Are the production assistants who round up and corral the grubs called "grub wranglers"?

But such grub-gulping also raises a tricky etymological question: Why do we call food "grub"?

"Grub," which first appeared in English as a verb, derives from the Old English "grybben," (to dig). In fact, we still use "grub" this way when we say, "I'm grubbing around for something to wear to the grub-eating contest."

When medieval peasants grubbed in the dirt, they often uncovered the larvae of beetles. So people started calling these squishy critters "grubs."

By a similar verbal process, the verb "dig" also became a noun, meaning a place of excavation and even a site carved out for living, as in, "From his fancy digs on Beacon Hill, he could see the Big Dig" (not to get in any digs at Boston or anything).

While those poor peasants were grubbing around in the dirt, they also found food. Well, yeah, there were those grubs of course, but there were also roots, bulbs and even potatoes. So "grub" came to mean any food found by digging and, eventually, any kind of food at all.

But why do we call money or resources given to someone starting up a business enterprise a "grubstake"?

Let's begin with "stake." (Author's Warning No. 2: If you're an animal rights activist, you may want to turn to the crossword puzzle.)

Back in medieval days, bored lowlifes would sometimes tie a bear or bull to a stake, set dogs on the poor creature and then bet on whether the dogs or the animal would prevail. (Today, we call such unsavory gambling a "prediction market.") Those who bet on the poor beast tied to the stake were said to have a lot "at stake," so "stake" came to mean a wager.

Flash forward to the gold fields of California in 1849. Local storekeepers would give food (grub) to newly arrived miners in exchange for a percentage of any gold the miners found.

The miners would then play poker using their food as a wager. So this food became known as a "grubstake."

Eventually, the food concept dropped away and "grubstake" came to denote any funds or resources available to someone starting up a business or enterprise, such as, say, a grub-wrangling service for reality TV shows.
