Here is an example:
"light" and "night"
Both words have the same stressed vowel sound ("i") and the same ending sounds ("t").
Other examples of perfect rhymes include:
* "moon" and "June"
* "flower" and "power"
* "cry" and "sky"
* "dream" and "scream"
It's important to note that eye rhyme, where words are spelled similarly but pronounced differently, is not considered eternal rhyme. For example, "love" and "move" are not perfect rhymes because the vowel sounds are different.
