One of the most fantastic things about England is the regional expressions. As a logophile, I get exceptionally excited about new words. My favourite one so far is “mardy,” a northern word meaning something akin to grumpy or sulky.
“You’re certainly mardy before your coffee.”
Right behind this is “chunter,” which is a kind of constant grumble. You might chunter as you do the housework, for instance.
“Quit your chuntering, you mardy bum.”
As you can see, English English is often related to “having a moan.” It’s a kind of cheerful misery, perhaps inspired by a sense of solidarity against the frequent grey skies.
