* Sound is subjective: What one person hears as an "are" sound might be slightly different from what another person hears.
* Phonetics is complex: There are many subtle variations in pronunciation, even within the same language.
* Words are constantly changing: New words are invented and old ones evolve, changing their pronunciation.
Instead of trying to list all words, let's look at some examples:
Words with the "are" sound:
* Care: The "a" sound is similar to the "a" in "father".
* Share: Same "a" sound as "care".
* Dare: Same "a" sound as "care".
* Hair: The "ai" sound is pronounced similar to "are".
* Pair: Same "ai" sound as "hair".
Words with the "air" sound:
* Fair: The "ai" sound is pronounced similar to "air".
* Chair: Same "ai" sound as "fair".
* Pair: Same "ai" sound as "fair" (although it can also be pronounced like "hair").
* Stair: Same "ai" sound as "fair".
* Bare: The "a" sound is pronounced similar to "air".
This is just a small sample of words with these sounds. There are many more examples depending on how you define the specific sounds.
If you have specific words in mind, it would be helpful to give me those, and I can tell you whether they contain the "are" or "air" sound.
