Distinguishing Innen, Drinnen and Rein in German

A1A2B1

After this lesson you can clearly distinguish **innen**, **drinnen** and **rein** and use each of them correctly in everyday German sentences.

In this lesson you learn how innen, drinnen and rein are different and how to use them correctly. All three are about something being “inside”, but they belong to different word types and are used in different situations.

1Overview

Word types and core meaning

WortWord typeCore meaning
innenadverb / adjectivedescribes a property on the inside
drinnenadverbdescribes “being inside a house / room”
reinverb particlemovement from outside to inside

Remember: innen and drinnen usually describe a state (where something is), rein describes movement (where something is going).

2Innen

innen means “on the inside” and often describes properties or states inside an object or space.

Typical uses

  • After the verb sein and similar verbs: „Das Auto ist innen sauber.“
  • As the opposite of außen: „Die Tür ist außen alt, aber innen neu.“

Examples

  • Das Gebäude ist innen modern.
    (The interior of the building is modern.)
  • Der Kuchen ist innen sehr weich.
    (The inside of the cake is very soft.)
  • Innen ist es viel heller als draußen.
    (Inside it is much brighter than outside.)

Note: innen is often used with things that clearly have an outside and an inside (buildings, objects, food, etc.).

3Drinnen

drinnen also means “inside”, but it is especially used for closed spaces: houses, apartments, rooms, offices, etc.

Typical uses

  • When talking about staying in a room: „Die Kinder sind drinnen.“
  • Often contrasted with draußen.

Examples

  • Es ist laut drinnen.
    (It is noisy inside the house / inside the room.)
  • Die Katze schläft drinnen.
    (The cat is in the house and sleeping.)
  • Drinnen ist es kühl, draußen ist es heiß.
    (It is cool inside and hot outside.)

Note: Use drinnen mainly for people and animals inside buildings or closed rooms.

4Rein

rein is a short form of hinein or herein and is a separable verb particle. It means “to the inside”, so a movement from outside to inside.

Typical uses

  • In commands: „Komm rein!“, „Geht alle rein!“
  • With verbs like gehen, kommen, bringen, tragen.

Examples

  • Komm schnell rein!
    (Come inside quickly!)
  • Ich bin schnell rein gegangen.
    (I quickly went inside.)
  • Kannst du den Stuhl reinbringen?
    (Can you bring the chair inside?)

Note the separation of the particle:

  • Present: „Ich bringe den Stuhl rein.“
  • Perfect: „Ich habe den Stuhl reingebracht.“
