r-schwa

Core Rule

R-controlled reduction occurs when r appears in an unstressed syllable, causing the preceding vowel to weaken toward /ər/. The vowel loses its full quality and becomes centralized.

Articulation Guide

Relax the jaw, slightly open the mouth, and let the tongue curl subtly toward the postalveolar area. Airflow is smooth and light, with no vowel lengthening.

Word Analysis

iron /ˈaɪərn/: stress on the first syllable; the r-colored vowel is reduced. irony /ˈaɪərəni/: the medial syllable is fully weakened with r coloring.

Pitfall Alerts

Do not pronounce a full /e/ or /o/ before r, and avoid deleting the r sound. Spelling variants like ir/er/or often converge in weak forms.
