The word height rhymes with white, kite, might, and light.
If you pronounce it hythe then you are pronouncing it incorrectly.

“Until the end of the seventeenth century, highth or heighth were its standard spellings. The word was formed in Old English from high, plus -th, the exact analogue of width, breadth, and length. If word history were the only consideration, we all ought still to be using highth.

The reason why we don’t comes down to dialect pronunciation in parts of Northern England in Middle English times, in which the -th ending was pronounced as /t/. In Southern England, it was said instead like the initial th in thumb. During the seventeenth century, the Northern form triumphed over the Southern, and the spelling followed suit. (Width and length didn’t follow because final dt is not a common consonant cluster in English and is hard to say.)

However, heighth continued to be widely heard. Charles Dickens used it frequently — as here in Great Expectations: “Pip, I wish you ever well and ever prospering to a greater and a greater heighth”. It still exists in several English dialects down to the present day. It has also survived in parts of North America, which have tended to cling to older pronunciations.

Because of its odd history, we can hardly argue that highth is truly an error, more an archaism. Though nearly everyone now spells it height, it’s not that uncommon to hear it said as “heighth” among educated people in North America, and some authorities there consider it to be a permissible variant.”

‘I could care less’ makes sense, only if you stress the ‘could’.
I /could/ care less [but I don't].
I couldn’t care less (because I care the least I can already).
I could care less (because this isn’t the least I can care about this). “Your point being?” is the correct response.

The other two words I have heard mispronounced lately…

– ‘innernet’ instead of internet (I notice that even news readers pronounce it wrong!)

- ‘sodder’ instead of solder.

Yet these same people somehow manage to pronounce words like interview with a ‘t’ and soldier with an ‘l’.

hītth rules!

Some of my pet peeves are “irregardless”, “lay” (as in “I’m going to lay down for a nap”), and “I could care less”, instead of “I couldn’t care less”.

eg. ” i have a pencil and a paper and i am going to make a draling. ”

my girlfriend does it all the time, but it gets worse whenever she visits baldamorl. you know, the capital of murulun.

I often get irritated when I hear the word pronounced “hythe”. My father was a stickler on correct pronounciation and claimed that those who mispronounced words were simply lazy.

As well as allowing heighth:

I never heard them until about 12 years ago here in California and since then I have been vexed by them daily.

As long as they exist in the dictionary, we are all doomed!

I would like to ask anyone who knows the answer, though.

Pronouncing “else” as “elks” is a part of Southern accent?

My favorite actor, a South/North Carolina native but have lived in New York more than 20 years, says so when he acts the Southern character or reads an audiobook set in the South.
