It means the Alpha star in the Wolf constellation, as someone said. :)

lup[b]us[/b] lup[b]i[/b] lup[b]i[/b] lup[b]orum[/b] lup[b]o[/b] lup[b]is[/b] lup[b]um[/b] lup[b]os[/b] lup[b]e[/b] lup[b]i[/b] lup[b]o[/b] lup[b]is[/b] Lupus, lupi (that's the entry you read in every Latin dictionary) is a male regular noun of the 2nd declension. In the first row you found the nominative case: [i]lupus[/i] means [i]wolf[/i] [b]as the subject in the sentence[/b]; lupi means wolves as the subjects in sentence. Example sentence: [i]Lupus necat homines[/i] = [i]the wolf kills the men.[/i] In the 2nd row you find the genitive case: [i]lupi[/i] means [i]of the wolf[/i] and [i]luporum[/i] means [i]of the wolves[/i]. In the 3d row you found the dative case: [i]lupo[/i] means [i]to the wolf[/i] and [i]lupis[/i] means [i]to the wolves[/i]. In the 4th row you found the accusative case: [i]lupum[/i] means [i]wolf[/i] and [i]lupos[/i] means [i]wolves[/i][b] as the object in a sentence[/b]. Example sentence: 1) [i]Homo necat lupum/lupos[/i] = The man kills the wolf/wolves. 2) [i]inter lupos[/i] = [i]among the wolves[/i]. In the 5th row you found the vocative case: [i]lupe[/i] means [i]"Oh wolf!"[/i] and [i]lupi[/i] means [i]"Oh wolves!"[/i]. In the 6th row you found the ablative case. Example: [i]ab lupo[/i] = from the wolf; [i]ab lupis[/i] = [i]from the wolves[/i].

Also the last three are: Lupis Lupos Lupis

I see, thanks for the clarification. I defer to your knowledge of Latin.
