This module teaches the retroflex consonant group: ट ठ ड ढ ण. The tongue curls slightly back for these sounds, which makes them different from the dental group taught later.
Learn to recognize ट ठ ड ढ ण. These letters belong to the retroflex group. The visual goal is to keep them separate from the dental set त थ द ध न, which you will learn later.
Practice these sounds slowly. Most prompts use simple examples. For ण, this lesson uses a teaching syllable because common Hindi word-initial examples are limited.
