Questions & Answers about Lift ne radi, idemo pješice.
Why use radi (from raditi) here? I thought it meant working at a job.
You are right that raditi means to work a job, but in Croatian, it is also the standard verb to use when a machine, device, or system is functioning. So ne radi is exactly how you say a machine is broken or out of order.
Is lift a borrowed word? Do Croatians actually say this?
Yes, lift is a loanword from English and is the most common way to say elevator in everyday Croatian. You will also see the native Croatian word dizalo on official signs or in formal writing, but lift is completely standard in spoken language.
How does pješice translate to 'on foot'? Is there a preposition missing?
Pješice is an adverb that means 'on foot' all by itself, so you do not need to add a preposition. You might also hear the slightly shorter version, pješke, which means the exact same thing.
Why is there no word for 'we' before idemo?
In Croatian, the pronoun mi (we) is usually dropped because the verb ending in -mo already makes it perfectly clear who is doing the action. You would only add mi here if you wanted to emphasize that WE are walking, as opposed to someone else.
