How short would you consider too short to log as a "book" you read?

My logic is that if it's available on this app (or any other) as a book, then it's a book but I also low key feel a little bit like I'm cheating when I count a tiny ass novella towards my overall reading goal for the year.

Some people are out here reading 100 books a year, that are 300-500 pages. And I've read 20 books so far in January but quite a few are novellas... one of them was 8 pages lololol.

Where do you draw the line?

I’m working on a list of fantasy romance books that could be considered Romantasy, but we’re published from before the coin of the term Romantasy.

Any recs?

This mostly stems from seeing the phrase “plot armor” show up in loads of different PB forums recently — especially surrounding a surprising character death or in comments like “felt there was too much plot armor” (someone please tell me in their own words what this means 🙏). This led to a more general curiosity around popular bookish terms, how they’re coined, and where they’re used. I’m a 20-something-year-old who’s barely active on social media and therefore not very connected to BookTok/Bookstagram, which I’m assuming is the reason for my knowledge gap, but I’ve noticed them flowing into in-person discussions recently (my cousin said “MMC” to me the other day and I was so confused until she clarified) so am feeling a bit out of the loop, despite being an avid reader from a young age!

While the meanings of some such terms can be determined through context clues, with some I’m truly clueless (I have no idea what TLDR means). To all my fellow readers — where do you see these bookish terms coined and how do you see them develop? Do you use them? Do you think they’re helpful tools for bookish discussions or do you feel they’re just fleeting and trendy?

Bonus points if you add and define your most-used in the comments to help me expand my bookish vocabulary! 🤓📖
