「get」と「become」の違い

The sunset earlier this week was beautiful! Take a look at that!

• × It's getting autumn, so the sunsets are getting more beautiful.
• ◯ It's becoming autumn, so the sunsets are getting more beautiful.

It's true that "get" has the same meaning as "become", but it must be used with an adjective. It can't be used with a noun.

◯ Since it's becoming cooler, I feel it's more comfortable.
◯ Since it's getting cooler, I feel it's more comfortable.

"Cooler" is an adjective, so both of these are OK, just like "more beautiful" in the first example.

× As I get more comfortable, I am also getting a more productive worker. <- "worker" is a noun
◯ As I get more comfortable, I am also becoming a more productive worker.

I hope that I can bring you more blog posts this month than last month.
