This is just my take, not saying it's gospel. But as I see it, BTC is the first successful use of blockchain tech.
So, breaking it down: blockchain is basically "block + chain".
Block: it’s about securing a specific action or record so it can't just change whenever someone wants.
Chain: this is linking things up in a techy way, which is what blockchain is all about.
What We Think About the Terms Blockchain and Bitcoin

Check out these links if you wanna avoid confusion. They give a brief history of blockchain and Bitcoin.

https://en.wikipedia.org/wiki/Blockchain
https://www.forbes.com/sites/digital-assets/article/the-history-of-bitcoin-who-invented-it
These articles are super useful to get a grip on the basics.
Great resources for the OP but there’s more to uncover.
Look into Bitcoin's prehistory, the timeline of key moments since ’79. Blockchain has been around longer than some think, but Bitcoin was the first to really decentralize it.
If you’re saying it can’t change at will, that’s kinda tricky. I mean, it suggests some approval could lead to manipulation.
Maybe ‘tamper-proof’ is a better term. If it gets messed with, it won’t accurately represent the data anymore.
You could also ask ChatGPT about the history.
Blockchain didn’t just pop up overnight; there were loads of tries before Bitcoin worked. Satoshi nailed it, but only he knows why he named it Bitcoin.

TL;DR: A blockchain is literally a chain of blocks. Bitcoin is just a name.
Blocks group transactions, and those blocks connect sequentially into a chain. It’s pretty simple when you think about it.

If we’re talking only about Bitcoin, there’s a distinction between 'Bitcoin' and 'bitcoin'.
Bitcoin is the network; bitcoin is the currency on that network. Not everyone gets that difference.

Honestly, I don’t think the name origins are that important anymore. We should focus on using this tech and improving it.
Names don’t matter as much as security and investment.
Block means a group of transactions, and chain is how these blocks connect. Each block has a unique hash that links to the next, like a chain. Messing with any block would break that chain.
Come on, do we really need to analyze this? It’s pretty obvious.
Blocks and chains were terms before blockchain existed. A block can mean any group, and a chain means a connected series of anything.
You nailed the definitions! A block is a set of unchangeable facts, and a chain links them mathematically.
Satoshi used ‘chain of blocks’ before 'blockchain' became common, and it’s true that Bitcoin was the first to succeed with this tech.
I think Satoshi had this in mind way before we even got here. He made the name easy to remember, kinda like branding.
It’s amazing how this idea came from such smart people in the cypherpunk scene.

With Satoshi, if he didn’t explain it in the white paper or emails, we can only guess.
There’s some interesting analysis about why he chose the name Bitcoin, but it’s not from him.
Blockchain is pretty clear if you look at how data is structured.
When you hear blockchain, you think of chains of blocks. And ‘bit’ existed before ‘byte’ it’s just short for binary digit.
It’s all about the tech connecting these blocks. That’s why people see Bitcoin as the first real success of blockchain.
Others didn’t make it because they lacked decentralization and openness.
Just a heads up: it’s actually the other way around.
‘Byte’ came from ‘bit’, not the reverse. So ‘bit’ is the original term.
