English will get you through most workdays in Nairobi without trouble — it's one of Kenya's two official languages. Swahili is the other: a Bantu language with heavy Arabic influence from centuries of Indian Ocean trade, spoken as a first or second language by well over 100 million people across East Africa. You won't need fluency, but a handful of phrases, used naturally, is the difference between being a visitor and actually settling in. Here's what people really say.

Greetings (you'll use these constantly)

SwahiliMeaning
Habari?How are things? (general, all-purpose greeting)
Nzuri / SalamaGood / all fine (the standard reply)
Mambo? / PoaWhat's up? / Cool (more casual, used with peers)
Asante (sana)Thank you (very much)
Karibu (sana)You're welcome / welcome

The two words worth learning first

Pole — not "sorry" for a mistake, but sympathy: said when someone's had a rough day, missed a bus, or just looks tired. And rafiki — friend — which gets used more freely and more sincerely in Kenya than the English equivalent.

You don't need fluency to make an impression — a genuine "Habari?" with eye contact does more than a textbook-perfect sentence delivered stiffly.
