[color=red]1-He writes some stirring poetry.
Can’t that sentence be used in two different contexts:
[color=darkred]a-As praise, meaning all the poetry he writes is stirring.
and in a context where “some” implies “not all”:
[color=indigo]b-He writes some stirring poetry. But the rest of the poetry he produces is pretty commonplace and dull.
Gratefully,
Navi.
