There is a little water in the pot.
There is some water in the pot.
What is the difference between them?
How can I distinguish these sentences?
I am a bit confused.
“A little” has greater emphasis on there being a small amount than “some.” In that sense, “a little” is less than “some.”
For example, someone who leaves a pot on the stove for far too long and comes back might say “there is a little water in the pot” to express greater relief at a near miss of a much more dangerous situation, than “there is some water in the pot” which someone might say when there’s still plenty left – not too much that it’s in danger of boiling over, and not so little that it’s in danger of burning.
