If it's a Germanic word that makes it unlikely to come via French, without it clearly being a French loanword. And very basic words are unlikely to be borrowed; it's mostly modern or learned words that tend to get borrowed. And of course, if the Luxembourgish form clearly differs from the German form, you can also be fairly sure it must be relatively old.
