==Proper notation of PIE phonemes==
People here are confused between how phonemes are represented in attested languages versus protolanguages. While it's true that, for example, a proto-sound like *p is a "phoneme" and that it may be represented as */p/ when pronounced as such, it's not true that these symbols are simply interchangeable with IPA notation. The phoneme *h2 **CANNOT** be represented in IPA notation as */h2/ whatsoever because "h2" is not a valid IPA symbol! Depending on the theories of the IEist in question regarding the pronunciation of *h2, however, the sound may be represented as some universally recognized IPA symbol (such as /x/, for example, a velar fricative). Mixing up these notations belies vast ignorance of the topic. Less editing, more reading. 24.78.208.183
