V vs Na: The Critical Distinction

This is the #1 struggle for Czech learners. When do you use v (in) and when do you use na (on/at)?

The Golden Rule

Default to V

When in doubt, use v. It works for ~80% of locations. Only use na when you know the word requires it.

Basic Meanings

Preposition	Basic Meaning	Think of it as...
v/ve	in, inside	Enclosed spaces, containers
na	on, at	Surfaces, open areas, events

When to Use V (Default)

Cities & Countries

• v Praze (in Prague)
• v České republice (in the Czech Republic)

• v hotelu (in the hotel)
