Learn Italian: C'è ancora un faro da posizionare. - There is still a spotlight to position.

In Italian, when you want to describe a noun as something that 'needs to be done' or 'is to be done', you use the preposition da followed by an infinitive verb. Here, un faro da posizionare translates to 'a spotlight to be positioned' or 'to position'.

I learned that faro means 'lighthouse'. Why is it translated as 'spotlight' here?

Faro originally means 'lighthouse', but in modern Italian it is widely used for any strong, directional light. Depending on the context, it usually means a car's 'headlight' or a theater 'spotlight'.

Could we put ancora at the very end of the sentence?

It is much more natural to keep ancora (still) right after the verb it modifies, which in this case is c'è. Saying C'è un faro da posizionare ancora would sound quite awkward to an Italian ear.

How would the sentence change if there were two spotlights left?

You would need to change the singular c'è (there is) to the plural ci sono (there are), and make the noun plural: Ci sono ancora due fari da posizionare.
