What does dug mean?
Dug serves two distinct purposes in English. Primarily, it functions as the past tense and past participle of dig, describing the act of breaking ground, excavating earth, or searching through something: a gardener dug a hole for the sapling, or investigators dug into old records. It can carry figurative weight too, as when someone 'dug their heels in' to signal stubbornness, or 'dug deep' to find inner reserves of effort. Separately, dug exists as a noun naming the teat of an animal's udder — a usage rooted firmly in agricultural and veterinary language. The noun sense feels rural and old-fashioned compared to the everyday verb form, yet both are centuries old and fully standard. Its brevity and hard consonants give it a blunt, physical quality well suited to its meanings, which are all about contact with earth or animal husbandry.
Made a hole or hollow by digging; excavated or moved earth.
"She dug her hands into the cool soil and planted the seedlings."
Standard irregular verb form; universally understood across all varieties of English.
A teat or nipple on the udder of a female mammal.
"The vet examined each dug to make sure the cow was nursing properly."
Chiefly agricultural or veterinary register; sounds rustic in casual conversation.
Applies only to the noun sense referring to animal teats; the verb form has no plural.
"The sow had twelve dugs, enough to feed all her piglets."
The same three letters that describe breaking ground with a shovel also name the business end of a cow — English rarely keeps its hands so clean.

Etymology of dug
The verb dug derives from dig, whose origins lie in Middle English, likely influenced by or related to Old French diguer, though the ultimate root is uncertain. The noun dug comes from Middle English dogge or dugge, meaning teat, possibly imitative or from Scandinavian sources cognate with Swedish dägg. Both forms have been stable in English since the medieval period, with no major semantic shifts.
