Great topic!  I never realized the actual 'silver chair' took up only one chapter of the whole book. Though the title I thought of more metaphorically, not literally. 

I think if I were to pick an alternative title for Silver Chair,  I would choose something along the lines of what C.S Lewis was suggesting, maybe Under the Ruins, suggesting their journey underground. 

I was also thinking of the title The Lost Prince,because the whole book was really about finding Rillian. Or Aslan's assignment (though for some reason that one seems a little different from the rest of the title's) 

You could also do the format of LWW,  The Prince, the city and the Serpent.   

The last one I have is The four signs. This title very much portrays what the characters have to do. 

Or how about The Wilderness North of Narnia, The Autumn Narnia Journey,  Overworld and Underworld, or The Lady’s Enchantment?  I’m not sure if all of these titles work, but I think they might be a start.

Here's something I wrote in the Prince Caspian title thread, which applies to this one too.

None of the other books mention Narnia in the title so I feel this shouldn't either.

Honestly, I vote for keeping the book's title. The silver chair may not be the biggest part of the story, but it's still fairly important and the scene that features it is highly dramatic. More importantly to me, The Silver Chair is a cool sounding title and none of the suggestions I've heard sound better to me.  

But if people really want suggestions for a title that reflects the story's overall focus, I have one. It's boring, even more of a boring title than Prince Caspian, which at least sounds kind of lyrical. But here it is.

Puddleglum

@col-klink, I agree, the title is pretty cool and does its job as is.

However, for the sake of speculation, here's a few: 

Darkness in the North

The Underworld Menace

The Forbidden Quest (after all, they go without Trumpkin's permission).

The Green Serpent

I'm really enjoying all the suggestions here and have finally come up with one myself — not really original, as it combines two other people's ideas.

Two of the suggested titles I like the most so far are The Four Signs and The Green Serpent (thanks, KingEdTheJust and Cleander!). But still neither of those felt quite right to me on their own until it came to me just earlier that we could combine a piece of each — how about The Signs and the Serpent ...? That brings in two of the most important elements of the plot without giving away any major spoilers. (We learn about the serpent early on, when the children are told the story of Rilian's mother's death, so it's not a big giveaway to know from the start that there is one in the book somewhere.)

It's also a title that has a nice ring to it (rhythm and alliteration), fits well with the titles of the other Chronicles, and to me sounds intriguing enough that I would definitely want to read it! There's a real sense of mystery and danger there, which the story itself has in bucketloads, but the title The Silver Chair doesn't really convey that feeling — certainly not the element of menace, which is a pity in what to me is one of the "darkest" in tone of all the Chronicles.

I just remembered that one of the chapters of The Silver Chair has my suggestion for a title (Puddleglum) so that's off the table. I mean you can have the title of a chapter be the same as the book's title, but none of the Narnia books do, I think.

Great discussion idea, @Courtenay.

I've actually always really liked the title The Silver Chair; it's very mythic, perhaps the most mythic-sounding of all the titles, and very mysterious. (So mysterious we don't actually get many answers about it IN the book, as Courtenay pointed out. ) I think that really fits the Arthurian romance vibes we find in the book.

That said, @KingEdtheJust's suggestion of The Four Signs is giving me chills and I really like that as well. It doesn't have quite the mythic quality that The Silver Chair does, but it still has the mystery and it captures the sweep of the whole book better.

Your suggestion of The Lady's Enchantment is also interesting, @Narnian78, because it's a bit of a red herring — at a glance, the title makes it sound like the lady in green is the one under an enchantment, not Rilian. (And perhaps she is, but that is another discussion for another thread for another time. ).

@rose

The enchantment comes from the Lady so it is actually hers. Or perhaps a clearer title would be The Enchantment of Rilian.  I always liked the way the BBC Narnia showed it with the woman becoming a snake in the woods.  Maybe Rilian Under Magic would work too.  The spell is one of the most interesting parts of the book. 

I actually haven't thought of this. I do like the plot line of The Silver Chair (though it is a bit slow at times).

Maybe a good title would be The Prince in the North or Remember The Signs.

I started thinking about how Lewis named his other books, and I noticed they have specific nouns, person or thing, for the title: magician's nephew, Lion Witch wardrobe, Prince Caspian, Dawn Treader, silver chair, horse boy, last battle. They are very straight forward and not rambling. I think that's why I like these five suggestions. They really would fit lined up with the other books. But I do like "The Silver Chair." It's very mysterious, and the chair was definitely part of the enchantment process.

What about "The Enchanted Prince"?

Or is that too much of a spoiler?

  I searched the whole internet for someone who would agree with me on this! Yeah, it was really weird for me when I finished that chapter and the chair was already destroyed, with no more explanation about it at all. 

@courtenay , I actually liked "The Wild Waste Lands", it's pretty cool to me. @kingedthejust , "The Lost Prince" is also excellent in my opinion, once the disappearance of Rilian is what drives the novel's plot. I personally would suggest "The Serpent's Charm", I think it would match the story (and it kinda has a Christian reference). 

  First time posting here haha

@calormenwarrior Welcome to the forum. There is a lot to talk about with Narnia as well as Netflx's coming up adaption.

I don't think I would have thought of The Serpent's Charm. It is true that the Lady of the Green Kirtle uses charm or hypnosis to make her victims forget, like she made Prince Rilian forget that he was a prince. She even made the gnomes forget about their place in Bism, that's why they're so sad. She also made Eustace, Jill, and Puddleglum forget about their quest, and distracted them with hot baths and soft beds by sending them to the giant castle of Harfang. And at another time, she made Prince Rilian, Puddleglum, Eustace, and Jill forget about Narnia and the whole overworld. Then she does turned into a serpent, and we've learned that she was the same serpent that killed Ramandu's daughter, Rilian's mother. So I can kind of see where you're going with the title.

Good to see this discussion growing. 

Someone said earlier that the current title refers to something that appears in only one chapter. I thought about that, and realised that lots of book titles, play titles and film titles also do this - referring to an incident or object that doesn't show up until well into the story.
