영어의 /r/과 모임

The /r/ is the most controversial of all the consonants in English. The history of its development accounts for the many variations we find. Earlier /r/ was a trilled sound, then a fricative sound, both clearly consonantal in acoustic value. During the seventeenth century, the consonantal aspects of the sound seem to have weakened and the sound became more and more vocalic, so that today it closely approximates a vowel. This paper aims to examine closely the relation between /r/ and vowels. In other words, it attempts to investigate the effect of /r/ on preceding vowel sounds, and establish the R vowel system in English. Accents of English can be labeled either 'rhotic' and 'non-rhotic' according to whether Irl is pronounced in final and preconsonantal position or not. Typically, RP is non-rhotic and GA is rhotic. We could find that there is no fundamental difference between general vowels and R vowels. Vowels are pronounced according to a special variation of the system of long and short vowels. Briefly, what has happened is that short vowels have coalesced with a following /r/ to produce new varieties of long vowel, while long vowels have developed a shwa glide from the vowel to /r/, and this has replaced the /r/ itself. All varieties of English have taken part in this change to some extent, and the differences among dialects concern the degree to which it has been effected. In rhotic English something of a consonantal Irl remains after a vowel; in non-rhotic English this /r/ has completely disappeared. In conclusion, English R vowels are as follows: ?:(r), ?:(r), ?:>:(r), ??(r), i?(r), u?(r), ?i?(r), ?u?(r), ?(r).
