I have noticed something but I would like to check it with you.

What do you think: is there any (but literally any) difference in pronunciation or something related to pronunciation between:

right and write and Wright (Mr. Wright)

whole and hole

weight and wait

wrath and rath (circular forth)

wreck and reck (care)

knew and new

wring and ring

knight and night

kneed and need

and similar to that


[The question is one foot deeper than a normal question of this type. So I do not think about a naïve answer to this.]

Does English have a color in it?
Yes they all sound exactly the same.

Naïve or not, I have no idea what you're talking about. Sorry!
Students: Are you brave enough to let our tutors analyse your pronunciation?
I think I understand your question.

The answer is "No". There is absolutely no difference, not even the most subtle hint of a shade of a nuance of any difference whatsoever between the pronunciation of write and right, night and knight, or any other such groups you might care to list.

Homophones they are called
the problem with English spelling is that we borrow and have borrowed an infinite amount of words over the years but have never been good about changhing the original orthography when we take these words into our writing system; thus, we have many words that don't seem to conform to any particular systematic way of representing sound in letters. If you look more closely, you can see patterns for certain sound representations. For example, 'ck' is only used to represent the [k] sound at the end of a word in spelling. This can be seen in words like book, stack, flick, pick, etc. At least some of these spellings of words might be linked to this phenomena. The difference in spelling can also be seen as an advantage though. Despite being pronunced the same way, the words that you introduced are definately different words so the different method of spelling eliminates confusion in writing if the context in which the word appears would not provide enough detail to distinguish which word is being used. You might want to take up some etymological study and look at the root of words, especially those from Latin, Greek, and French that would not only greatly assist you in deducing the semantics behind new words but also to reason out the spelling.
It's late here, maybe I should have used some simpler sentence structures here, especially if the question was posted by a non-native speaker.

this also reminde me of a joke me and my friends have that we alway's use while driving.

"I wanna turn left, right?"

"Right, left."
Students: We have free audio pronunciation exercises.
Some dialects of Scots and Scottish-English do distinguish some of those, because they pronounce the -gh as [ x ] .
