What does grub mean?
“Grub” is a versatile word whose common informal meaning is food or a meal, especially in phrases such as “a good grub.” Its older, literal meaning is a small larva, particularly the larva of a beetle, which is often found in soil or decaying organic matter. As a noun, it can also refer dismissively to an unpleasant or contemptible person. The verb “grub” means to search or rummage, as in “grubbing for worms,” and can describe a determined search for food, money, or information. A further traditional sense is to obtain a living through whatever work or means are available. The word is interesting because it connects an insect term, an informal vocabulary of eating, and figurative ideas of persistent searching. Its compact form and shifting meanings make it especially useful in casual writing and speech.

Where does grub come from?
The noun descends from Old English “grubs,” meaning an insect larva, while the related verb comes from Old English “grybban,” meaning to dig or search. Both belong to a Germanic word family associated with digging or hollowing out, cognate with German “Grube,” meaning a pit or hole. The culinary sense and the figurative sense of searching became especially familiar in modern English.
