Questions & Answers about Θέλω ακόμα ένα βιβλίο στα ελληνικά.

What does ακόμα mean here? Does the sentence mean “I still want a book in Greek” or “I want another book in Greek”?

In this sentence, ακόμα ένα functions together and means “one more / another”.

• Θέλω ακόμα ένα βιβλίο στα ελληνικά.
  → I want another / one more book in Greek.

If you wanted to say “I still want a book in Greek” (emphasizing still), you would usually change the word order:

• Ακόμα θέλω ένα βιβλίο στα ελληνικά.
  → I still want a book in Greek.

So:

• ακόμα ένα βιβλίο = another book, one more book
• ακόμα θέλω = I still want

Is there any difference between ακόμα ένα βιβλίο and άλλο ένα βιβλίο?

They are very close in everyday use and often interchangeable, both meaning “another / one more book”.

• Θέλω ακόμα ένα βιβλίο.
• Θέλω άλλο ένα βιβλίο.

Both can be understood as “I want one more book.”

Very slight nuance (not always important in speech):

• άλλο ένα can more clearly suggest “an additional, different one”.
• ακόμα ένα is more like “one more (on top of what we already have)”, without stressing “different”.

In normal conversation, you can safely treat them as the same here.

Why is it ένα and not ένας or μία?
