The respectful ending ండి must be clear. Do not reduce చెప్పండి to చెప్పండ or రండి to రండ. In మీరు, the vowel మీ is long. In వెళ్లండి, pronounce the doubled ళ్ల carefully. Respectful speech is not only grammar; a gentle tone and moderate speed make the words sound sincere.

Dropping the final vowel in ండి forms. Pronouncing మీరు like short మిరు. Confusing చూడండి and చూడు. Saying respectful words with a harsh tone. Not holding doubled consonants like ళ్ల.

When meeting someone for the first time, start with మీరు. If the other person invites casual speech later, you can adjust.

Remember: మీరు + ండి = safe Telugu. If you are unsure, use respectful pronouns and polite verb endings.
