ir r-sound
Core Rule
The ir sound is an r-controlled vowel. When i is followed by r, the short /ɪ/ is neutralized and becomes /ɜːr/ (AmE) or /ɜː/ (BrE). Spelling varies, but the sound remains stable.
Articulation Guide
Relax the tongue, slightly raise or curl the tip toward the alveolar ridge without touching. Keep lips neutral and let the airflow pass smoothly.
