The meaning of "Hallows"

" When asked "What does 'Deathly Hallows' mean?" J.K. Rowling responded, "Any clarification of the meaning of 'Hallows' would give away too much of the story - well, it would, wouldn't it? Being the title and all. So I'm afraid I'm not answering."^[12]. She also declined to say what her two other shortlisted titles had been, at least until after publication. Two similar titles had been registered as trademarks by representatives of Warner bros in 2003-2004, Hallows of Hogwarts and Hogwarts Hallows ^[13]. The release of the title has resulted in considerable speculation as to its possible meanings ^[14][15][16]

Hallow is a word usually used as a verb, meaning "to make holy or sacred, to sanctify or consecrate, to venerate".^[17] However, in Harry Potter and the Deathly Hallows, the word hallows appears as a noun. In modern English, the word is used as a noun in "All Hallows' Day" or "All Saints' Day," which is the day after Halloween or "All Hallows' Eve". Halloween was also the day Harry's parents were killed, and subsequently, he was scarred by Lord Voldemort. Hallows can refer to saints, the relics of saints, the relics of gods, or shrines in which the relics are kept.^[18][19] Since the essence of these saints or gods were often considered present at their shrines and in their relics, hallows came to refer to the saints or gods themselves, rather than just their relics or shrines. Hallow is not to be confused with hollow, such as in Godric's Hollow. "

Now this is why, I really adore Wikipedia.
