r-sound
Rule Core
R-controlled vowels occur when a vowel is followed by r, causing the vowel to lose its pure sound and merge with /r/ into a single unit: ar, or, er, ir, ur. The presence of /r/ reshapes the vowel through tension and retroflex coloring.
Articulation Guide
Curl or retract the tongue slightly without touching the palate. Lips stay neutral to slightly rounded. Airflow is continuous; do not separate the vowel and /r/.
Word Analysis
- advisory: the -or- is /ɔr/, not a long /o/.
- allure: -ure is /ʊr/, not /juːr/.
- alternative: -ar- is /ɑr/, not /æ/.
Pitfalls
er/ir/ur often reduce to /ər/ in unstressed syllables. Different spellings may share the same sound; rely on stress and morphology, not letters alone.
Phonics Breakdown
Retract the tongue slightly; blend the vowel and /r/ together
