beaver /BEE-vər/. noun or verb. A large, amphibious rodent. To work industriously and eagerly at something.
wolf /wuulf/. noun or verb. A large, dog-like mammal. A voracious or cruel person. To gulp down.
mudlark / mudlarking. noun or verb. Rarely, slang for a hog. Traditionally, a street urchin or scavenger (or the activities of such); now, hobbyists and treasure seekers who search in muddy areas along rivers. Also, a generic name for various birds that like muddy environments, particularly the magpie lark and Australian slang for a racehorse that excels on muddy tracks.
faze /FAYZ/. verb. To perturb, disturb, unsettle or fluster. Unrelated to phase (from the Greek phainein, to show), with which it is commonly confused—see the Mark Twain example below—faze derives from the dialectal feeze(to alarm or frighten), from Old English fēsian (to drive away, to banish).
cuckold /KUK-əld/. noun or verb. A man whose spouse has been unfaithful or the act making a cuckold of someone. Of late, a scornful political term embraced most strongly by white nationalists to describe their opponents, often abbreviated as cuck. From Middle English cukeweld (same meaning), from Old French cucuault: cocu (cuckoo) + pejorative suffix -ault.
The interesting aspect of the etymology is its roots in the behavior of the female cuckoo bird, some of which lay their eggs in the nests of—and leave them to be cared for by—other birds, leading to the figurative word we are becoming all too familiar with today.
cark /kark/. verb or noun. To vex, burden or harass…or to suffer from such. Also: a trouble, a burden, a weight. From Latin carcare (to load a wagon), from Latin carrus (wagon). Less commonly, to die, originally an Australian colloquialism, possibly derived from the caw of the carrion crow.
