पहुँच गए? deserves special mention. Indians expect a message confirming safe arrival after any journey, and not sending one causes genuine worry. A parent or friend will ask, and the expected reply is simply पहुँच गया or पहुँच गई. It is a small courtesy with real emotional weight.

There is no standard, and the same word appears many ways. A few conventions dominate.

• Long vowels are doubled inconsistently — kya, kyaa and kia all appear.
• The word नहीं is written nahi, nahin or nai depending on the writer.
• Retroflex consonants are rarely marked, so ट and त both become t.
• English words are spelled normally and mixed in without comment.

For a learner this is a real difficulty when reading, because the same word looks different in every message. The upside is that nobody will criticise your spelling, since there is nothing to be correct against.

The daily good morning message is a genuine Indian institution. Family and neighbourhood groups fill each morning with greeting images, flowers, deities and inspirational quotes, and older relatives send them faithfully. Not responding is fine, but understanding that this is affection rather than spam changes how you read it.

Indian WhatsApp groups have their own norms, and a few are worth knowing.

• Family groups are large, active and include relatives you have never met.
• Forwards circulate constantly — jokes, health advice, religious images, and a fair amount of misinformation.
• Leaving a family group is a social event and may cause genuine offence.
• Replying to individual messages within a busy group is done using the reply-quote function, since threads move fast.

The phrase फ़ेक न्यूज़ has entered Hindi directly, and WhatsApp forwards are widely recognised in India as an unreliable source, discussed and joked about openly.

One further habit worth understanding is the missed call, which survives from the era of expensive call rates and remains in wide use. A deliberate single ring means call me back, I have arrived, or simply I am thinking of you, depending on who sent it and when. It costs nothing and communicates a surprising amount, and receiving one from an Indian friend is not a mistake or a dropped call.

Voice notes are extremely common in Indian WhatsApp use, often preferred over typing, so your spoken Hindi gets tested more than you might expect. Speak slightly slower than in person, since compression degrades audio and the listener cannot see your face. The phrases here are worth practising aloud rather than only reading, because you will very likely need to say them into a microphone.

• Not sending a message confirming you have arrived safely.
• Reading morning forwards as spam rather than as affection.
• Leaving a family group without warning.
• Expecting consistent Roman Hindi spelling.
• Forwarding health or news claims without checking them.
