r-controlled
Core Rule
R-controlled vowels occur when a vowel is followed by r, altering the vowel’s usual long or short sound. The vowel and r merge into a single sound unit: ar, er, ir, or, ur. The r no longer sounds separately but reshapes the vowel.
Articulation Guide
Retract the tongue slightly with no firm contact to the palate. Keep the lips relaxed and airflow smooth. The key is a sustained, centralized sound colored by r.
Word Analysis
- airfield: air /ɛr/, the a is modified by r.
- are: pronounced /ɑr/, not the long a name.
- barn: ar /ɑr/, open mouth, strong r-coloring.
Pitfall Alerts
Do not split the sound into vowel + r. Note that er/ir/ur often share the same sound despite different spellings.
