NOTE: I speak a rhotic variety of English.
I am struggling with how to explain r-coloured vowels/vocalic R to teachers during a presentation on the phonemes of English. Many grapheme-phoneme lists include "er", "ar" and "or" as Vocalic R/Bossy R/Vowel Rs or an equivalent term. Most do not list "air", "ear”, ire" or "oor/ure”.
When I search materials from the linguistics world I have seen one description where /ɚ/ is called a syllabic consonant and the other sets are vowel+consonant (Ladefoged?). However, in other sources I see the same three listed as r-coloured vowels: /ɚ, ar, or/. It makes sense that /ɚ, ɝ/ is listed as it's own separate thing but I do not understand why /ar/ and /or/ get a mention when /ɛr, Ir, aIr, ur,jur/ do not.
Furthermore, if you are asking kids & teachers to identify sounds and use letters to represent sounds, are there a bunch of r-coloured vowels or is there one and the rest are vowel+consonant?
For example,
- Are there two sounds in "car" or three: c-ar or c-a-r?
My personal preference is say that there is one r-coloured vowel--ɚ--and the rest are vowel+consonant.
For example, surely the 'a' in 'ar' can have the same phonological representation as the 'a' in "father" and "water," which makes c-a-r quite logical.
However, I am clearly going against the prevailing teaching that says r-coloured vowels are to be taught as their own phonemes (like diphthongs, I guess?).
Maybe I am missing something.
- What is the reasoning for singling out /ar/ and /or/?
- Are the third formants more affected by the /r/ than the others?
- Are r-colored vowels actually vowels or are they vowel+consonant?
