I can't distinguish the meanings of gerunds.
The gerund "eating"
The gerund phrase "eating slowly"
Do they refer to the same activity? I think they might both refer to eating slowly, but I think they refer to two different activities.
Are they not different facts, the same as just walking and walking quietly are different?
This doesn't seem the case for nouns. Yellow stone and hard stone can refer to the same thing, not different concepts.
