Compared to other languages, English is in practice pretty indifferent with regards to parts of speech. The lines are often blurry. I'm curious about the following phrase:
It's fun.
Usually, I'd think that "fun" is a noun. For instance I can have lots of it. However, there are phrasings where it is used much like a qualifier.
It was a fun ride.
Just looking at the structure, it could be either an adjective or a noun in the phrase in question.
It's fun/milk. It's fun/nice.
My first impulse was "noun" but seeing how there is no article and how most phrasings that express roughly the same would use an adjective, I am not so sure anymore. Here are my questions.
- What part of speech is "fun" in the phrase?
- Do native speakers clearly perceive it as noun or adjective respectively or would both readings make sense on an intuition level?
