Usage tips
Word structure
'Drinnen' (inside) is a combination of 'darin' (in it/inside it) and 'innen' (inside). It developed from the old form 'da-rinne' and literally means 'there inside'.
EXAMPLE
Lass uns reingehen, drinnen ist es wärmer.
Let's go in; it's warmer inside.
Use as an adverb
'Drinnen' (inside) is an adverb and cannot be connected with a noun like a preposition. It stands on its own and answers the question 'Wo?' (Where?). You say 'Wir sind drinnen' (We are inside), but not 'Wir sind drinnen das Haus' (We are inside the house).
EXAMPLE
Wo ist die Katze? Sie ist drinnen und schläft auf dem Sofa.
Where is the cat? It's inside, sleeping on the sofa.

drinnen vs innerhalb
within / inside
'innerhalb' and 'drinnen' can both mean that something is not outside. However, 'innerhalb' describes more precisely that something lies within the boundaries of a specific area, for example within a house, park, or country. It is usually used with a noun. 'drinnen' is used more in everyday language when someone or something is inside a room, building, or enclosed area. The words can be confused because both point to an inner location. A simple rule is: 'drinnen' sounds natural for rooms and buildings; 'innerhalb' sounds more precise when there are clear boundaries.
drinnen
Omar bleibt drinnen, weil es draußen stark regnet.
Omar stays inside because it is raining heavily outside.
innerhalb
Die Eltern warten, bis alle Kinder innerhalb des Schulgeländes sind.
The parents wait until all the children are within the school grounds.
