I can't distinguish the meanings of gerunds.
- Eating (gerund) (=the action of eating)
- Eating slowly (gerund) (=the action of eating slowly)
Do they refer to the same activity? (That is, is eating slowly eating?) Or eating and eating slowly refer to two different activities?
I think eating and eating slowly refer to two different activities because maybe I heard someone saying just walking and walking quietly are different. And we say the fact that we eat and the fact that we eat slowly are two different facts. That's why I'm thinking two gerunds (eating and eating slowly) refer to two different concepts.
I think it's quite far from examples of nouns. Because yellow stone and hard stone can refer to the same thing but eating slowly and eating delightfully, I think, refer to two different concepts.
If eating and eating slowly can refer to the same concept, eating slowly is eating and eating delightfully is eating so eating slowly can be eating delightfully, which is, I think, wrong.
And as someone said in the comment, "eating is fun" and "eating slowly is fun" are definitely different.
Actually that means a lot to me. Compare:
- Walking slowly is for her. (because walking slowly makes less noise)
- Walking is for her (because she wants me to lose weight)
