Questions & Answers about Infla la cambra d'aire.
Here it is most naturally understood as a command: Inflate the inner tube.
That is because infla can be:
- the tu imperative of inflar = inflate!
- also the 3rd person singular present = he/she/it inflates
In isolation, the form is ambiguous, but in a short instruction like Infla la cambra d'aire., it is read as an imperative.
Catalan often omits subject pronouns when they are not needed.
So instead of saying:
- Tu infla la cambra d'aire
Catalan normally just says:
- Infla la cambra d'aire
This is especially common in commands, where the subject is usually understood automatically.
