How do you pronounce Heigh?

"Heigh" is a tricky one because it doesn't really exist as a standalone word in standard English. It's usually part of a larger phrase like "Heigh-ho!" or "Heigh-diddle-diddle!"

The pronunciation of "Heigh" in these phrases is similar to the word "high" but with a slightly more drawn-out, almost sing-songy quality.

So, you would pronounce it like "hahy" but with a longer "a" sound.
