Hi, you're welcome. Expressions built with more than one word are difficult. On the other hand, Duolingo often gives "composite" meanings when you hover over a word. A more kolibri-like way of looking at sentences may be helpful.
Is this considered a complete sentence in French? I think it's an incomplete sentence or sentence fragment in English. It would be used only as a casual answer to a question or something - "Why is that guy always staggering?" "Because he drinks." :/
