I had a discussion with a colleague at work.
I was not able to explain why the things are the way they are. I explained him the meanings and so on, with the reason "because". Topped with "take it or leave it". However, I want to be more professional than that.
Also, I worry that I do not properly understand the difference between "adjective" and "adverb" in English.
- This is hard work.
"Hard" is adjective (sits with "work" - a noun).
- I work hard.
"Hard" looks like an adjective (see above) but it works like an adverb (sits with "work" - verb).
Also, we can transform adjectives to adverbs using the suffix "-ly":
bad -> badly
However, the following is definitely incorrect:
- I work hardly.
While the following is correct, but it means pretty much the opposite of 2:
- I hardly (=barely) work.
