Yaldi is a Scottish slang interjection expressing excitement or joy.
Where does yaldi come from?

Yaldi is distinctly Scottish slang, but its origins are somewhat uncertain. It came into use sometime at least by the mid-2000s. It’s possible that the word comes from a mispronunciation of the 19th- century Scottish slang laldy.
Laldy originally means “a beating,” but it is often used in the expression give it laldy,or “do something enthusiastically.” Onesuggestion is that yaldi might be a combination of yes and laldy to express lots of enthusiasm.

Yaldi is often used as an expression of joy and happiness on its own, sort of like Hooray!or Yaas! It can also be used in the expression give it yaldi, like give it laldy, meaning “do something with a great deal of vigor,” particularly when it comes to singing or dancing.
As an exile living in England, I still use Scots words, much to the natives confusion. If not used a language will die, so keep gaein it laldy
