voiced th

Core Rule

The voiced th /ð/ is a voiced fricative where the vocal cords vibrate. It appears frequently in high-frequency words like this, that, and mother, making it essential in phonics instruction.

Articulation Guide

Place the tongue lightly between the teeth, keep the mouth relaxed, let air flow continuously, and activate the vocal cords. Touch your throat to feel vibration.
