What does "Filiane" mean?

Question

I am learning Latin from Collar and Daniell's FIRST YEAR LATIN. In LESSON IV: THE GENITIVE CASE TO DENOTE POSSESSION, an exercise is given (sentence translation).

Some examples:

• Līberatne? Līberō, portāmus. (Hopefully translates to Is he freeing? I am freeing, we are bringing.)
• Fīliās incolārum līberant (They are freeing the daughters of the inhabitants.)

But, there is one sentence I do not understand:

Fīliane Galbae litterās exspectat?

I have no idea what Fīliane means. I have checked it in several dictionaries, including Lewis and Short, to no avail.

From what I have read, fīlia means daughter, but it has a -ne ending added to it? (To a noun? What?!)
My only guess is, this is a mistake and the sentence should be this instead:

Fīlia Galbae litterās exspectatne? - hopefully: Is Galba's daughter expecting some letters?

Is that correct?

Answer 1

Your analysis is correct: this is fīlia "daughter" + -ne "?".

The trick is, -ne can attach to any word, not just verbs. In fact, it usually attaches to either the first word, or the most emphatic word, whatever that might be. Since nōn often comes at the beginning, nōn-ne became common enough that you'll often see it analyzed as a word of its own, rather than a combination! Similarly, satis-ne is common enough that it's often contracted to satin'.

So your translation is spot-on: "is Galba's daughter expecting some letters?"
