Another interesting word of Scottish origin that I encounter from time to time is “chimbley” for “chimney”.
Several colloquialisms for rural southerners come from the Scots well:
Hillbilly - from the casual term for a follower of King William III of Orange in the 17th century. This is the William of “William and Mary” who fought the return of Catholic rule to England.
Redneck - supporters of the National Covenant of 1638 declared that Scotland embraced democratic church governance and rejected the Church of England. Some signed in blood and wore a red kerchief around their necks.
Cracker - from crac, crack, craic, kracken; a word that goes way back at least as far as Old High German, passed to Anglo-Saxon, to Old English, to Gaelic. Across the ocean crack has come to mean “good times” including friends, merriment, music, food and drink. As a pejorative the meaning of cracker leans toward someone who is a boastful, frivolous, liar.
“Redneck - supporters of the National Covenant of 1638 declared that Scotland embraced democratic church governance and rejected the Church of England. Some signed in blood and wore a red kerchief around their necks”
This may have historical veracity, but I think the use of the word, “redneck” comes from the red bananas miners used in the coal mines of Appalachia.
Where I live I hear the word “chimly” for “chimney.” “Chimly” shows up in the poetry of Robert Burns — definitely a Scottish origin.
