"Fine" as an adjective means:
- of very high quality; very good of its kind.
- very thin or narrow.
- [in Cricket] directed or stationed behind the wicket and close to the line of flight of the ball when it is bowled.
I found the following usage of the term "fine" in my textbooks, that say:
- I am fine.
- Fine adjustment screw [the part of microscope]
- Throughout history, people have cut up the bodies of living things to find out what is inside. Their study was limited to what the eye could see, the fine details inside the organs were unknown.
Which sense (from the definitions mentioned above) does these three usages suggest?
Does saying "I am fine" really mean I am having high quality?
Doesn't that mean thin or narrow when I say "fine adjustment screw"?
How can a detail be of a highly quality when I say "...the fine details inside the organs."?
What are the other usage example of "fine"?
