rhotic ar
Core Rule
The ar r-controlled vowel occurs when a is followed by r, producing /ɑr/ in American English or a lengthened /ɑː/ in non-rhotic accents. The key logic: r reshapes the vowel, pulling it back and adding r-coloring.
Articulation Guide
Retract and slightly raise the tongue body; curl the tongue tip back without touching the alveolar ridge. Jaw relaxed, airflow steady.
Word Analysis
- clarification: clar- is stressed; ar is fully r-colored.
- compare: ar in -pare carries the vowel weight.
- marxism: ar stays /ɑr/, never /æ/.
Pitfalls
Do not confuse ar with short a or uh. Even in unstressed syllables, the r-coloring remains.
Phonics Breakdown
Retract the tongue, curl the tip slightly, voice /ɑ/ with r resonance.
Sound Reference
- Anchor the tongue position before voicing the vowel.
- Practice minimal pairs like car–cat.
