How many words do you really need to know to communicate?

Anyone starting a new language almost automatically looks at the number first: a good dictionary contains tens of thousands of entries, and it quickly feels like you'd need to master most of them just to communicate at all. That impression holds people back more than it helps. Over the past few years, I've spent a lot of time observing how people actually speak: in a café, in small talk with neighbors, when asking for directions in an unfamiliar city. The result is reassuring: everyday language is surprisingly economical. A small, recurring core of words carries most of what we actually need to say and understand in daily life.

How Much Language Fits Into a Few Hundred Words

Linguists who analyze large collections of spoken language texts arrive at similar figures across many languages: the roughly 100 most common words, things like I, you, be, have, good, not, do, already make up a substantial part of an average conversation, often around half. With the approximately 1,000 most common words, you already cover three quarters to four fifths of everyday spoken language in many languages. These are numbers you can build up in a few weeks of focused learning, not years. Anyone who knows 2,000 to 3,000 well chosen words can already move through most everyday situations remarkably fluently.

Why Selection Matters More Than Quantity

However, not all common words are equally useful, and not all useful words are equally common. Someone planning a trip probably needs the word for bill, platform, or pharmacy sooner than some word that ranks higher on a frequency list but rarely comes up in their own life. Ten words that fit your own situation are often worth more than a hundred random ones. That's exactly why simply memorizing vocabulary lists often achieves little: it lacks any connection to your own reality. A word you need and use in a real conversation tends to stick, while a word crammed in isolation usually fades again within a few days, and a calm learning environment also makes a difference in how well that works.

What's Really Enough for Specific Situations

In a café, you get by with a very manageable set: a drink, a polite phrase, a few numbers for the order and the price, plus phrases like I'd like or the check, please. For small talk, a few dozen words about weather, how you're doing, and simple follow up questions are often enough, combined with a handful of set phrases you can use again and again. And anyone asking for directions mainly needs direction words, a few place names, and the ability to politely ask someone to repeat themselves if the answer comes too fast. None of these situations calls for thousands of words, more like a handful of well fitting building blocks.

It looks different as soon as more nuanced or specialized topics come into play: explaining a medical exam, discussing politics, or reading a novel. Depending on the level of demand, that requires several thousand to tens of thousands of words; native speakers often have a passive vocabulary of 20,000 words or more. But that's a different goal from the ability to communicate in everyday life, and the two shouldn't be confused with each other.

Ten words that fit your own situation are often worth more than a hundred random ones.

What Norimo's Dialogues Are About

This is exactly the distinction Norimo focuses on. Instead of working through long, alphabetically sorted vocabulary lists, we put situational dialogues at the center: conversations in a café, checking in at a hotel, small talk with colleagues, because clear dialogues come to mind faster in a real conversation than isolated grammar knowledge. The words and phrases they contain are deliberately chosen based on how often you actually need them in that exact situation, not on how complete a list looks. The goal isn't to collect as many words as possible, but to practice the right ones so you can actually recall them when it counts. People who learn this way often notice, sooner than expected, that they can communicate long before they've built up an entire vocabulary.
